Question

Find the length of the side of a square with an area of 121 in
`{?}^(2)`

Answer 1

A square has all its side equal

The area of the square is given by

A = l x l

Substituting the value of A= 121

then

`\begin{gathered} \text{Area = L X L} \\ \\ 121=L^2 \\ \\ L^2\text{ = 12}1 \\ \\ L\text{ =}\sqrt[]{121} \end{gathered}`

L is the square root of 121

L = 11 inches
