Answer:
- width: 7.26 ft
- length: 8.26 ft
Step-by-step explanation:
Let w represent the width of the rectangle. Then w+1 is the length, and the area is ...
w(w+1) = 60
w^2 +w + 0.25 = 60.25 . . . . eliminate parentheses, complete the square
(w +0.5)² = 60.25
w +0.5 = √60.25
w = -0.5 +√60.25 ≈ 7.26 . . . . . feet
w+1 = 8.26 . . . . feet = length
The dimensions of the rectangle are 7.26 feet by 8.26 feet.
