A parking lot has 916 parking spaces that are shaped like parallelograms. The base of each space is 10 feet, and the height of e

dmitriy555 [2]

The area of a parallelogram is $A=bh$

$A=10(18.5) \\ A=185$

I am assuming you're asking for the entire parking lot, so you would have to multiply the above area by 916

$185(916) = 169,460 ft^{2}$

So the answer is (D)
