To answer this question with the choices given, you would substitute the possible answers into your work for the base and the height of each dimension on the entire campground.
To find the length of the campground, you multiply each choice by 5 because there are 5 campsites.
For the width, you add each choice to 4.
Then you multiply the total length by the total width to see if your answer is 950 square yards.
See the attached picture for all the work.
