Well, if you're trying to find the area, the answer of <em>b </em>would be 4,700 feet. If you are trying to find the perimeter, the answer of <em>b</em> would be 330.
Explanation:
The area would be 4,700 because when you are multiplying, you must take the two numbers (or it can be even more) and then multiply each number together (also known as multiplacation-pretty basic.) If you would like to find the perimeter, you would then need to find this kind of math by adding all of the numbers-together, but times two. If you were trying to find the answer to <em>b</em>, then you would need to add 75 times 2, which is 150. You would also add 60 times 2 to this equation, making the number 180. You would then add 150 plus 180 and then you will get 330. The difference why each of these are different numbers is because area and perimeter are different-two kinds of math. Now you can answer your problem by choosing whether it was a perimeter shape or a shape with area. Now solve it!
