Question

The area of square-shaped feild is 6400 m ki power 2. Find each of the following:
1. Side
2. Perimeter
3. Fenxing cost along its boundry at the rate of $3.50 per m.

Answer 1

$area = 6400 {m}^{2}$
Area
$= side \times side$
hence,
$6400 = {side}^{2}$
$side = \sqrt{6400}$
$side = 80m$
Now Permieter,
$permeter = 4 \times side$
$perimeter = 4 \times 80$
perimeter=320
