Question

The area of a room is $65\frac{1}{4}{m}^2$.If its breadth is $5\frac{7}{16}m$, what is its length?

Answer 1

Give: Area of a room $=65\frac{1}{4}{m}^2$

Breadth $=5\frac{7}{16}m$

Area of rectangle $=$ length $\times$ breadth

$\therefore$ Length $=$ Area $÷$ Breadth

$=(65\frac{1}{4}÷5\frac{7}{16})$

$=\frac{261}{4}÷\frac{87}{16}$

$=\frac{261}{4}\times \frac{16}{87}$

$=\frac{3}{1}\times \frac{4}{1}$

$=12m$

Hence, Length of the rectangle $=12m$
