Question

The sides of a rectangle are in the ratio 2:5.if its width is 5 cm find its area

Answer 1

Hey friend,

Here is the solution :-

First, we have to find the length so that we can find the area, so :

$let \: the \: length \: be \: x \\ \\ then \: according \: to \: question \: \\ \\ \frac{2}{5} = \frac{x}{5} \\ \\ now \: by \: cross \: multiplication \\ \\ 5 \times x = 2 \times 5 \\ \\ 5x = 10 \\ \\ x = \frac{10}{5} \\ \\ x = 2$

Here we get the length = 2cm.

Now we can find the area of the rectangle :

$area \: of \: a \: rectangle \: = length \: \times \: breadth \\ \\ length \: = 2cm \: \: \: \: breadth \: = 5cm \\ \\ 2cm \times 5cm = {10 \: cm}^{2}$

➡ So, the area of the rectangle is 10 square cm.
