Answer:
6 feet.
Step-by-step explanation:
Dimensions of the Pool =80 feet long by 20 feet wide
Area of the walkway =1344 square feet.
If the width of the walkway=w
- Length of the Larger Rectangle =80+2w
- Width of the Larger Rectangle =20+2w
Area of the Walkway =Area of the Larger Rectangle - Area of the Pool

-20%
work:
(24-30):30*100=
(24:30-1)*100=
80-100=-20
Answer:
59/20 cups
Step-by-step explanation:
5 3/10
8 1/4
Common denimainator is 40
5 3/10 = 5 12/40
8 1/4 = 8 10/40
Now we can subtract:
330/40-212/40=118/40
118/40= 59/20 cups
