Question

The length and breadth of a rectangle are $20cm$ and $10cm$. Find the ratio of the length to the breadth of the rectangle.

Answer 1

Step 1: Find the ratio

It is given that:

• the length of the rectangle $=20cm$
• the breadth of the rectangle$=10cm$

The ratio of two quantities $a$ and $b$ is written as $a:b$.

So, the ratio of the length to the breadth of the rectangle is $20:10$.

Step 2: Simplify the ratio

Let's convert this ratio into its simplest form:

The highest common factor (H.C.F) of the terms $20$ and $10$ is $10$.

Let's divide both the terms by $10$:

$\frac{20÷10}{10÷10}=\frac{2}{1}$

Hence, the ratio of the length to the breadth of the rectangle is $2:1$.
