| Square | A =s2 | s is the length of the side of the square. |
| Rectangle | A=LW | L and W are the lengths of the rectangle’s sides (length and width). |
| Triangle | A=12bh | b and h are the base and height |
Also, What is perimeter formula?
The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle. The perimeter, P, is: P=x+x+y+y.

What is TSA of cylinder?
Total Surface Area of Cylinder
The total surface area of a cylinder is equal to the sum of areas of all its faces. The Total surface area with radius ‘r’, and height ‘h’ is equal to the sum of the curved area and circular areas of the cylinder. TSA = 2π × r × h + 2πr2= 2πr (h + r) Square units.
How do we calculate area?
The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.
How do you calculate area and volume?
Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height.
How do you calculate total area?
Multiply the length of the base, b, by the height, h, to find the total area. The equation for the area, A, of a square or rectangle area can be written as: A = b * h. In our example, the base, b, is 12 inches, and the height, h, is 5 inches. Therefore, the area is 12 inches multiplied by 5 inches, or 60 square inches.
How do you calculate perimeter examples?
Explanation: Divide the area of the rectangle by the width in order to find the length of 14 feet. The perimeter is the sum of the side lengths, which in this case is 14 feet + 4 feet +14 feet + 4 feet, or 36 feet.
What is a formula of perimeter of rectangle?
The perimeter of a rectangle is twice the sum of its length and width and it is calculated with the help of the formula: Perimeter = 2(length + width). It is the measure of the total boundary of the rectangle.

What is CSA and TSA of cylinder?
The TSA of cylinder having its base radius ‘r’ and height ‘h’ is given by: Total surface area (TSA) of cylinder = Area of curved surface + Area of its two circular bases. Or, TSA of cylinder = CSA of cylinder + Area of its two circular bases. = 2πrh + 2πr2 sq. units.
What is the formula of the volume of a hollow cylinder?
The formula to calculate the volume of a hollow cylinder is given as, Volume of hollow cylinder = π (R2 – r2) h cubic units, where, ‘R’ is the outer radius, ‘r’ is the inner radius, and, ‘h’ is the height of the hollow cylinder.
How do you calculate the area of a rod?
A. =2πrh+2πr2 . Example 2: Find the total surface area of a cylinder with a base radius of 5 inches and a height of 7 inches.
How can you find the area of a rectangle?
To find the area of a rectangle, multiply its width by its height. If we know two sides of the rectangle that are different lengths, then we have both the height and the width.
What is the difference between area and volume?
The area is the measurement of the region covered by any two-dimensional geometric shapes. The volume is the space occupied by the three-dimensional object. Volume is measured for 3D(solid) figures. The area is measured in two dimensions i.e length and breadth.
How do you figure out the volume of a shape?
Volume is the amount of space a 3D shape takes up.
This is written as 1 cm³. You can work out the volume of a shape by multiplying height × width × depth. If the shape is made of cubic cm blocks, you can count the cubes to find the shape’s volume.
How do I calculate the area of a rectangle?
Explanation: To find the area of a rectangle, multiply its width by its height. If we know two sides of the rectangle that are different lengths, then we have both the height and the width.
How is volume measured?
Volume is the amount of space occupied by a sample of matter. The volume of a regular object can be calculated by multiplying its length by its width by its height. … The SI unit of volume is the cubic meter (m 3 ), which is the volume occupied by a cube that measures 1 m on each side.
How do you find area in square meters?
Multiply the length and width together. Once both measurements are converted into metres, multiply them together to get the measurement of the area in square metres.
What is perimeter example?
The perimeter is the distance around the object. For example, your house has a fenced yard. The perimeter is the length of the fence. If the yard is 50 ft × 50 ft your fence is 200 ft long.
What is the formula of area and perimeter?
The perimeter P of a rectangle is given by the formula, P=2l+2w , where l is the length and w is the width of the rectangle. The area A of a rectangle is given by the formula, A=lw , where l is the length and w is the width.
