Question

PLZ I NEED QUICK HELP!!! The lenght of a rectangle is equal to triple the width. Which system of equations can be used to find the dimensions of the rectangle if the perimeter is 86 centimeters?

Answer 1

We can represent the perimeter of a rectangle with

`2l + 2w = p`
where l represents the lenght, and w represents the width, finally p the peramiter.

`l = 3w \\ 2l + 3w = 86`
