Question

The perimeter of a square 16 cm, then its area is __________ cm².

Answer 1

$$\begin{gathered} \mathrm{As},\mathrm{the}\mathrm{perimeter}\mathrm{of}\mathrm{the}\mathrm{square}=16\mathrm{cm} \\ \mathrm{So},\mathrm{the}\mathrm{side}\mathrm{of}\mathrm{the}\mathrm{square}=\frac{\mathrm{Perimeter}}{4} \\ =\frac{16}{4} \\ =4\mathrm{cm} \\ \mathrm{Now},\mathrm{the}\mathrm{area}\mathrm{of}\mathrm{the}\mathrm{square}=\mathrm{Side}\times \mathrm{Side} \\ =4\times 4 \\ =16{\mathrm{cm}}^2 \end{gathered}$$

Hence, the area of the square is 16 cm².
