iren [92.7K]

Given:

Width of a rectangle = $2x+4$

Length of the rectangle = $6x+12$

To find:

The ratio of the width to the length.

Solution:

We need to find the ratio of the width to the length.

$\text{Required Ratio}=\dfrac{\text{Width}}{\text{Length}}$

Putting the given values, we get

$\text{Required Ratio}=\dfrac{2x+4}{6x+12}$

$\text{Required Ratio}=\dfrac{2(x+2)}{6(x+2)}$

$\text{Required Ratio}=\dfrac{2}{6}$

$\text{Required Ratio}=\dfrac{1}{3}$

$\text{Required Ratio}=1:3$

Therefore, the ratio of the width to the length is 1:3.
