Question

A parking space shaped like a parallelogram has a base of 18 feet and a height is 7 feet. A car parked in the space is 15 feet long and 5 feet wide. How much of the parking space is not covered by the car?

Answer 1

17/42 or 40.48% of parking space is not covered by the car

Explanation:

First we have to calculate the surface of the parking space and the car.

p = parking space

p = 18ft * 7ft

p = 126ft²

c = car

c = 15ft * 5ft

c = 75ft²

To find out how much parking space is not covered we first have to calculate what is covered, dividing the car by the parking space

75/126 = 25/42

to calculate the uncovered space we simply subtract 25/42 from 1

1 - 25/42 = 17/42

if we want it as a percentage we simply multiply it by 100

17/42 * 100 = 40.47%

17/42 or 40.48% of parking space is not covered by the car
