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

Verified Answer :

the length of each side can be found using pythagoras theorem:-

11.3^2 = 2x^2     where x = length od each side
x = sqrt( [11.3^2  / 2)
x =  7.99 meters

Answer:

The perimeter of the square is \(31.96\ m\)

Step-by-step explanation:

we know that

The perimeter of a square is equal to

\(P=4b\)

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

\(d^{2} =b^{2}+b^{2}\\d^{2}=2b^{2}\\d=b \sqrt{2}\)

In this problem we have

\(d=11.3\ m\)

\(d=b\sqrt{2}\) ------> solve for b

\(b=d/\sqrt{2}\)

substitute the value of d

\(b=11.3/\sqrt{2}\ m\)

Step 2

Find the perimeter of the square

\(P=4b\)

Substitute the value of b

\(P=4(11.3/\sqrt{2})=31.96\ m\)
