Question

Janet is building a rectangular pumpkin patch. The perimeter of the pumpkin patch is 100 meters. The width of the garden is 7 meters less than 2 times its length. Find the length and the width of the pumpkin patch.

Answer 1

Perimeter of a rectangle is 2L+2W
let L=L
W= 2L-7
2L^2 - 7L = 100
Factor it at find that L= -5.53 or 9.03
Length can’t be a negative value si answer is 9.03 for length.
Plug this value in for W=2L-7
W=11.06
