Question

A Parking lot has a length of 100 yards wide and a length of 200 yards. The parking lot will be expanded by increasing both the length and the width by r yards. The area of the expanded lot will be twice the area of the original lot. Which equation can be used to find r?

Answer 1

40,000

Explanation:

100x200=20,000

20,000x2=40,000

first we have to find the original are, then we know it gets doubled the size so we have to multiply that by 2, then we get 40,000.
