The perimeter of a garden is 70 meters. Find its actual dimensions if its length is 5 meters longer

[math_celebrity]

The perimeter of a garden is 70 meters. Find its actual dimensions if its length is 5 meters longer than twice its width.

Let w be the width, and l be the length. We have:
P = l + w. Since P = 70, we have:

1. l + w = 70
2. l = 2w + 5

Plug (2) into (1)
2w + 5 + w = 70

Group like terms:
3w + 5 = 70

Using our equation calculator, we get w = 21.66667. Which means length is:
l = 2(21.6667) + 5
l = 43.33333 + 5
l = 48.3333
