Question

Max is making a rectangular garden that is 5 feet less than twice it's width. If the perimeter of the garden is 89 feet, what will be it's dimensions?

Answer 1

Length = 2*width - 5
perimeter = 2(length + width)
89 = 2(2width - 5 + width)
89 = 6 width - 10
6 width = 99
width = 99/6 = 16.5 feet
length = 2*16.5 - 5 = 28 feet
