Question

Give a suitable unit used to measure the surface covered by the school playground.

Answer 1

1. Surface area: the area occupied by the surface is called the surface area.
2. SI unit of the surface area is a $\mathit{m}\mathit{e}\mathit{t}\mathit{r}\mathit{e}\mathbf{}\mathit{s}\mathit{q}\mathit{u}\mathit{a}\mathit{r}\mathit{e}\mathbf{\left(}{\mathit{m}}^{\mathbf{2}}\mathbf{\right)}\mathbf{.}$
3. The area of a school playground is neither too big, nor too small.
4. $metresquare$is a suitable unit to measure the area of a school playground.
5. Alternatively, one can use the unit $squarefoot\left(f{t}^2\right)$ to measure the area of a playground.

Hence, the surface covered by the school playground can be measured in $\mathit{m}\mathit{e}\mathit{t}\mathit{r}\mathit{e}\mathbf{}\mathit{s}\mathit{q}\mathit{u}\mathit{a}\mathit{r}\mathit{e}\mathbf{\left(}{\mathit{m}}^{\mathbf{2}}\mathbf{\right)}$ or in $squarefoot$.
