Asquare cement parking lot is being converted to a nature park. each side of the parking lot is 100 meters long. the plan is to reduce the side lengths of the lot by 8 meters each year to plant greenery. which function can be used to calculate the area of the cement parking lot, a, after t years?

Step-by-step explanation:

Let

t-----> the number of years

A-----> the area of the cement parking lot

we know that      

The function that represent this situation is

A=20,000 m2 per year

Step-by-step explanation:

we have that Volume (V) =300,000 m3, so V=A*h, where A=area (m2) and h=15m

V=A*h ⇒ 300,000m3=A*15m ⇒ A=300,000m3/15m ⇒ A=20,000 m2
