Question

Find the length of the side of a square-shaped farm whose perimeter is $60a(b+c)km$.

Answer 1

Given perimeter = $60a(b+c)km$
Let the side of the square-shaped farm be $s$ km.
In a square, all sides are equal.

∴ $s+s+s+s$ = Perimeter
⇒ $4s$ = $60a(b+c)$
$\therefore$ s = $60a(b+c)÷4$
⇒ $s$ = $15a(b+c)km$
