Question

The lenght of a rectangular garden is 10 meters more than twice its width.if the area of the garden is 1000 square meters,find its dimension

Answer 1

Answer:

Let w stand for width. Then length is 2w+10. So:

w(2w+10)=1000

2w�+10w-1000=0

w�+5w-500=0

(w+25)(w-20)=0

w=20,-25

The width is 20 meters, and the length is 50 meters.
