Find the width and length of the rectangle so that it has the given perimeter:
P = 60 inches, width is x, and length is 3x – 5.
:
The perimeter equation:
2(3x-5) + 2x = 60
6x - 10 + 2x = 60
6x + 2x = 60 + 10
8x = 70
x = 70%2F8
x = 8.75 is the width
then
3(8.75) - 5 =
26.25 - 5 = 21.25 is the length
:
:
Check the perimeter
2(21.25) + 2(8.75 =
42.5 + 17.5 = 60
