Question

What will be the number of unit squares on each side of a square graph paper if the total number of unit squares is $256$?

Answer 1

Determine the number of unit squares.

Given, that the total number of unit squares on square graph paper is $256$.

A square is a quadrilateral with all four sides equal and parallel to one another.

Find the number of the unit square on each side of a square on graph paper from the area of the square as follow:

$$\begin{gathered} \mathrm{Area}={\left(\mathrm{side}\right)}^2 \\ \Rightarrow 256={\left(\mathrm{side}\right)}^2\left(\mathrm{Given}\right) \\ \Rightarrow \mathrm{side}=\sqrt{256} \\ \Rightarrow \mathrm{side}=16 \end{gathered}$$

Hence, the required number of unit squares on each side is $16$.
