The area of a square field is 7200 m2. What is the length of its diag…

Area of square field = 7200 m²

Area of square = (side)²

Diagonal of square = \(\sqrt {2}\) × (side)

So,

Let the side of the square field be m

= m² = 7200

= m = 60√2

= Diagonal of square field = 60\(\sqrt {2}\) × \(\sqrt {2}\)

=  Diagonal of square field = 120 m
