Answer:
1. (2w-5) (w-3)= 55
2. 2w^2-11w+15= 55
Step-by-step explanation:
Solution:
1. W: the width
2w: the length
The area: (2w-5) (w-3)= 55
5 meters was subtracted from its length
3 meters was subtracted from its width
2. (2w-5) (w-3)= 55
2w^2-6w-5w+15= 55
2w^2-11w+15= 55
2w^2-11w+15= 55
2w^2-11w+15-55= 0
2w^2-11w-40= 0
(w-8) (2w+5)
w=8 or w = 5/2 (let's get rid of this root)
The width of rectangle is 8 meters
