Answer:
- 5 feet
- 22.4%
- 22 m
Step-by-step explanation:
1. The product of force and distance must be the same for each force. If the distance from the greater force is d, then it is 14-d for the lesser force.
135d = 75(14-d)
210d = 1050
d = 1050/210 = 5
The fulcrum must be placed 5 feet from the greater force.

2. The percentage change is ...
(772.80/996 -1) × 100% ≈ -22.4%

3. The product of the two dimensions must be 220 m². We note that 10 and 22 are factors of 220, and that 22 is 2 more than double 10.
The sides are 22 meters long. (The width is 10 m.)
