Question

If the area of a square is 100 square cm what is its perimeter

Answer 1

Answer:

area= side*side

$100 = side { }^{2} \\ side = \sqrt{100 = 10cm}$

perimeter =4*10=40cm

Answer 2

Answer:

40cm

Step-by-step explanation:

let side of sq be s

so , area =s²

then,s²=100cm²

=s²=(10cm)²

=s= 10cm

therefore,perimeter using 4s

therefore,perimeter using 4swe get,4×10=40cm
