Question

What is the area and perimeter of a square of 7½m​

Answer 1

Answer:

The area of a square of 7½m​ is 225/4 sq. m and the perimeter is 30 m.

Step-by-step explanation:

Given: Side of square = 7 1/2 m = 15/2 m

Find: The area and perimeter of a square.

Formula:

Perimeter of square = 4 × side

Area of square = side × side

Step 1: Find the perimeter

Perimeter of square = 4 × side = 4 × 15/2 = 2 × 15 = 30 m

Step 2: Find the area of square

Area of square = side × side  = 15/2 × 15/2 = 225/4 sq. m

Answer 2

Here the side of the square is given to be  7½m​

7½m​ = 7.5 m

We have to find the area and perimeter of the square

area = side × side

         = 7.5 × 7.5

        = 56.25 m²

perimeter = 4 × side

                 = 4 × 7.5

                = 30 m

Hence, the area and the perimeter of the square will be 56.25 m² and 30 m
