Question

Area =100 cm2 find its perimeter of square​

Answer 1

$\textrm{Area of Square = Side \times Side}$

$\longrightarrow\textrm{100 cm ^2 = Side \times Side}\longrightarrow\textrm{Side = \rm{\sqrt{100 \:cm^2}} = 10 cm}$

$\textrm{Perimeter of Square = 4 \times Side}$

$\longrightarrow\textrm{Perimeter of Square = 4 \times 10 cm = 40 cm}$
