Question

What is the side length of a square if it’s area is 49cmsquared? Also, what is it’s perimeter?

Answer 1

Step-by-step explanation:

Area of Square = ${s}^{2}$

=> $49 {cm}^{2} = {s}^{2}$

=> $\sqrt{49 {cm}^{2} } = \sqrt{ {s}^{2} }$

=> $7cm = s$

thus, side length of square is $7cm$.

And,

Perimeter = $4s$ = $4(7cm)$ = $28cm$

thus, perimeter of square is 28cm.

Answer 2

Answer:

Length=√Area

So here length = √49 = 7 cm
