Question

Represent the given condition using a single variable, x.

The length and width of a rectangle whose length is 15 centimeters more than its width.
The width of the rectangle is ____.

Answer 1

Please check the explanation.

Explanation:

Let suppose
`x` be the width of the rectangle.

As the length is 15 centimeters more than its width i.e.

`length = x+15`

Therefore, the width of the rectangle will be:

`x = length - 15`

CHECK BY EXAMPLE

Let suppose if the length of the rectangle is 20 cm.

Then the width of the rectangle will be:

x = length - 15

= 20 - 15

= 5 cm

Therefore, the width of the rectangle will be 5 cm.
