Question

Find the area and perimeter respectively of a rectangular plot of land whose length and breadth are $15.4m$ and $6.5m$ respectively.

• A. $100.10sq.m$, $43.8m$
• B. $43.8m$, $100.10sq.m$
• C. $4.38m$, $100,10sq.m$
• D. $1001.10sq.m$, $4.38m$

Answer 1

The correct option is A $100.10sq.m$, $43.8m$

$\Rightarrow$ Here, $l=15.4m$ and $b=6.5m$.

$\Rightarrow$ Area of rectangular plot $=l\times b$

$\Rightarrow$ Area of rectangular plot $=15.4\times 6.5$

$\therefore$ Area of rectangular plot $=100.10m^2.$

$\Rightarrow$ Perimeter of rectangular plot $=2(l+b)$

$\Rightarrow$ Perimeter of rectangular plot $=2(15.4+6.5)$

$\Rightarrow$ Perimeter of rectangular plot $=2\times 21.9$

$\therefore$ Perimeter of rectangular plot $=43.8m$.

$\therefore$ Area and perimeter of rectangular plot are $100.10m^2$ and $43.8m.$ respectively.

Hence option $\left(A\right)$ is correct
