Answer 1

$$\begin{gathered} \mathrm{Dear}\mathrm{Student}, \\ \mathrm{Let}\mathrm{there}\mathrm{are}\mathrm{x}\mathrm{unit}\mathrm{square}\mathrm{on}\mathrm{each}\mathrm{side}\mathrm{so} \\ \mathrm{Area}\mathrm{of}\mathrm{square}=256 \\ \mathrm{x}\times \mathrm{x}=256 \\ {\mathrm{x}}^2=256 \\ \mathrm{x}=\sqrt{256}=\sqrt{16\times 16}=16 \\ \mathrm{So}\mathrm{there}\mathrm{are}16\mathrm{unit}\mathrm{square}. \\ \mathrm{Regards} \end{gathered}$$
