Question

Eight square flower beds each of size $1\mathrm{m}$ are dug on a piece of land $6\mathrm{m}$ long and $3\mathrm{m}$ wide. Find the area of the remaining part of the land.

Answer 1

Find the area of the remaining land:

$\Rightarrow$ Area of land $=6\mathrm{m}\times 3\mathrm{m}$

$=18{\mathrm{m}}^2$

$\Rightarrow$ Area of eight square beds $=8\times 1$

$=8{\mathrm{m}}^2$

$\Rightarrow$ Remaining part of a land $=18-8$

$=10{\mathrm{m}}^2$

Therefore, the area of remaining part of the land is $10{\mathrm{m}}^2.$
