Answer:
width: 15 inches; length: 20 inches
Step-by-step explanation:
The equation tells you the product of width (x) and length (x+5) is 300, so you're looking for factors of 300 that differ by 5.
300 = 1·300 = 2·150 = 3·100 = 4·75 = 5·60 = 6·50 = 10·30 = 12·25 = 15·20
The factors in the last pair on this list differ by 5, so we have ...
- width = 15 inches
- length = 20 inches
