Question

If the area of a rectangle is 54 m2 and its breadth is 75cm Finds its length in metre

Answer 1

$\huge\mathsf{Given \ -}$

$\mathsf{Area \ of \ rectangle \ = \ 54 \ m^2}$

$\mathsf{Breadth \ of \ rectangle \ = \ 75 \ cm}$

$\large\mathsf\red{\boxed{1 \ m \ = \ 100 \ cm}}$

•°•

$\mathsf{1 \ cm \ = \ 1 \ / \ 100 \ m}$

$\mathsf{75 \ cm \ = \ 75 \ / \ 100 \ m \ = \ 0.75 \ m}$

$\mathsf\green{\boxed{Area \ = \ Length × Breadth}}$

$\mathsf{54 \ = \ Length × 0.75}$

$\mathsf{Length \ = \ 54 \ / \ 0.75}$

$<b>$
Area of the rectangle = 54 sq.m

Breadth of the rectangle = 75 cm
As 1 m = 100 cm
$1cm = \frac{1}{100} \: m \\ so \: 75 \: cm \: = 75 \times \frac{1}{100} \: m \\ = \frac{3}{4} m$
As we know the formula
Area of the rectangle = Length x Breadth
$54 = length \: \times \frac{3}{4} \\ length \: = \frac{54 \times 4}{3} \\ length \: = 72 \: m$
So The Length of the rectangle is 72 m
