The perimeter of a rectangle is 56 m. the length is 4 m more than three times the width. find the length and the width of the rectangle.

Width=x

length = 3x+4

perimeter = 56

To find the perimeter you have to add all the sides

So it will look like this:

x + (3x+4) + x + (3x+4) = 56

8x+8=56

8x=56-8

8x=48

x=48/8

x=6

The width is 6 m long

calculate length 3 (6) + 4

The length is 22 m long
