Question

The area of rectangle is 30 cm². If one of the sides is 6 3/4cm, find the other.
$6 \frac{ 3}{4}$
​

Answer 1

Answer:

4 4/9

Step-by-step explanation:

30= 6 3/4 X x. (x is breath)

30=27/4 X x

x=(30X4)/27

x=40/9

x=4 4/9

Answer 2

Answer:

$\text{Breadth of the other side}=\frac{40}{9}\text{cm}=\bold{4\frac{4}{9}\text{cm}}$

Step-by-step explanation:

Given: Length = $6 \frac{3}{4} \text{cm}$, Area = $30 \text{cm}^{2}$

Area of Rectangle: Length x Breadth

Therefore, $30 \text{cm}^2=6\frac{3}{4}\text{cm}\times\text{Breradth}$

$\therefore\text{Breadth}=\frac{30\text{cm}^2}{6\frac{3}{4}\text{cm}}\\ \\ \frac{30\text{cm}^2}{6\frac{3}{4}\text{cm}}=\frac{30\text{cm}}{\frac{27}{4}} \\ \\ \frac{30\text{cm}}{\frac{27}{4}}=30\text{cm}\times\frac{4}{27} \\ \\ 30\text{cm}\times\frac{4}{27} = 10\text{cm}\times\frac{4}{9} \\ \\ 10\text{cm}\times\frac{4}{9}=\frac{40}{9}\text{cm}=4\frac{4}{9}\text{cm}$
