Question

find the perimeter of square whose area is 2500m

Answer 1

$area \: of \: square = {a}^{2} \\ 2500 = {a}^{2} \\ a = \sqrt{2500} \\ a = 50$
$perimeter \: of \: square = 4. \alpha \\ = 4 \times 50 \\ = 200m$

Answer 2

Area of square=side²
→2500=a²
→a=√2500
→a=√50×50
→a=50.
Perimeter of square=4×side
=4×50
=200m.
