If the diagonal of a square is 11.3 meters, approximately what is the perimeter of the square

The perimeter of the square is

Step-by-step explanation:

we know that

The perimeter of a square is equal to

where

b is the length side of the square

Step 1

Find the length side of the square

The diagonal of the square is equal to

Applying the Pythagoras Theorem

In this problem we have

------> solve for b

substitute the value of d

Step 2

Find the perimeter of the square

Substitute the value of b

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
