Question

The area of a square is 16200sq m.Find the length of its diagonal

Answer 1

Given that area of square = 16200 sq. m

We know that area = (side)²

⇒ √16200 = side
⇒ 90√2 = side

Now, diagonal of square = √2 * side 
= √2 * 90√2
= 180 m 

Answer 2

Area =16200m2
Side of the square = x^2=16200
x=√16200
x=127.2m
Diagonal of the square =10√x
=10√127.2
=10×11.27= 112.7 m answer.
