Question

Five square flower beds each of sides $1m$ are dug on a piece of land $5m$ long and $4m$ wide. What is the area of the remaining part of the land?

Answer 1

The side of square bed $=1m$.

Area of square bed $=$ side $\times$ × \times side

$\Rightarrow$ Area of square bed $=1m\times 1m=1m^2$

$\Rightarrow$ Area of $5$ flower beds $=5\times 1m^2=5m^2$

Now,

Length of land $=5m$.

Breadth of land $=4m$

∴\thereforeTherefore, Area of land $=$ length$\times$breadth.

$=5m\times 4m$

$=20m^2$

Area of remaining part $=$ Area of land $-$ Area of $5$ flower beds.

$=20m^2-5m^2$

$=15m^2$
