Question

The length of a rectangle is three times it’s width, if the perimeter of the rectangle is 64ft what is the area

Answer 1

A = 192 ft2

Explanation:

`p=2l+2w`

`l=3w`

`p=2(3w)+2w=6w+2w=8w`

`64=8w`

`w=64/8 =8ft`

The area:

`A=lw`

`l=3w=3(8)=24ft`

`A=(24)(8)=192sqft`

Hope this helps
