Question

Find the perimeter of square whose area is 100 cm²​

Answer 1

Answer:

area if a square,=a2

so a2=100

and a=10

perimeter of a square = 4*a

so.... p=4*10

perimeter of a square =40cm

Answer 2

$\huge{\underline{\underline{\mathcal{\red{Solution}}}}}:-$

We know that Area of Square = a²

Here, a is the side of square.

Given perimeter is 100 cm²

= 100 = a²

= √100 = a

= a = 10cm

We know, Perimeter of the sqaure = 4a

So, 4 (10)

= 40 cm

So, the perimeter of square is 40 cm.
