Question

Mr. Lawrence is building a fence around his vegetable garden which is in the shape of a rectangle with the length of 30 feet and width of 40 feet. Mr. Lawrence completed the fencing in 12 hours.

What is the unit rate at which Mr. Lawrence put a fence around his vegetable garden?

Answer 1

11 2/3 feet per hour

Explanation:

You add up the lengths to find the perimeter.

30 + 30 + 40 + 40 = 140

Then you divide the lengths by the amount of time taken

140/12 = 11 2/3 or 11 8/12 feet per hour
