The area of a rectangle is 144cm squared. The length of the rectangle is 8 cm. What is the measure of the width of the rectangle
Gelneren [198K]
<h2>Greetings!</h2>

Answer:

The width is 18cm

Step-by-step explanation:

If the equation of the area of a rectangle is:

Area = length * width

Then you substitute in the values you know:

144 = 8 * width

To find the width you need to rearrange the formula to make the width the subject. Do this by dividing the area by the length:

Width = 144 / 8

Width = 18

So the width is 18cm
