Question

A rectangular garden has a perimeter of 92 feet. If the length of the garden is 1 foot greater than twice its width, what is the length of the garden in feet?

Answer 1

width = w
length,l  = 2w + 1

perimeter, p

p = 2w + 2l
92 = 2w + (2*(2w+1))
92 = 2w + 4w + 2
92 = 6w + 2
6w = 90
w = 15

so length of the garden
2w + 1
2*15 + 1
31 feet
