Question

A campground consists of 8 square campsites arranged in a line along a beach. The distance from the edge of a campsite to the water at the end of the beach is 5 yd. The area of the campground, including the beach, is 1220 sq yd. What is the width of one campsite?

Answer 1

The width of one campsite is 30.5 yards.

The campsite area has a 1220 square yards and a width of 5 yards.
If we divide 1220 by 5, we see that the total length of the campgrounds must be 244 yards.

Now, divide 244 by 8 and you will get that each campground is 30.5 yards wide.

(Unless, you forgot to include the distance of the campground with the given width, that would change our answer)
