Answer:
436 feet will not be covered by the hot tub.
Step-by-step explanation:
If the backyard is 10 feet by 50 feet (I am assuming that you meant 50, not 5o), then you would use the area formula.
A = L * W Area equals length times width
A = 10 * 50
A = 500 ft
Now let's find the area of the hot tub
A = L * W
A = 8 * 8
A = 64 ft
This means 64 feet of the backyard will be covered by the hot tub, but you must find the area <u>NOT</u> covered. To do this, subtract the two areas.
500 -- 64 = 436 ft
This means 436 feet of Tina's backyard will not be covered by the hottub.
