Solution

Transcript

Solution:

Let the length of the side of a square be x meter.

Area of square = \left(side\right)^2=x^2(side)2=x2

According to question,



x^2=441x2=441

\Rightarrow x=\sqrt{441}=\sqrt{3\times3\times7\times7}⇒x=441=3×3×7×7

x = 3 x 7

x = 21 m

Hence, the length of side of a square is 21 m.
