Question

The perimeter of a rectangular garden is 78 feet. the width is six feet less than twice the length. Find the length and width of the garden.

Answer 1

L=7.94 feet, W=9.88 feet

Explanation:

perimeter=78 feet

LxW=78

2L-6=W

substitute

Lx(2L-6)=78

2L^2-6L=78

2L^2-6L-78=0

factor

(2L-15.86)(L+4.95)=0

2L=15.88, L=7.94

L=-7.94 feet
