Question

The length of the side of a square whose area is 441sq.cm is ___

Answer 1

Answer:

21cm

Step-by-step explanation:

area of square=441sq.cm

therefore,

area of square = side^2

441 = side^2

√441= side .......... ( taking sq.root)

21 cm = side

therefore,

length of the side of square= 21cm.

Answer 2

Let Area of the square = A

Let side of the square = s

A = s × s

441 cm^2 = s^2 cm^2

s = under root(441) cm^2

s = 21 cm^2
