the perimeter of a rectangle is 24in. and its length is 3 times its width. what is the length and width of the recrangle?

the length of the rectangle is 6 and the width of the rectangle is 6

The length is 9 inches and the width is 3 inches

Explanation:

The dimensions can be found by creating a variable "x" for the sides of the rectangle, where x is the width, and because the length is three times the width, length is equal to 3x

We then set up an equation for the perimeter

p

=

2

l

+

2

w

and plug in our x values for length and width.
