Question

The length of a rectangle is 3 times its width. The rectangle’s width is 4 m. What is the area of the rectangle? Enter your answer in the box. m²

Answer 1

Answer: 48m²

Explanation:

We can set up an equation to find the length. Once we have the length, we can multiply it with the width to get out area.

`l=3w`

`w=4`

Now that we have our length and width, we can plug in width into our length and find the area.

`l=12m`

`w=4m`

`A=12m*4m=48m^2`
