The length of a football field is 120 yd. The width of the football field is 50 yd. Which is the correct unit of measurement to use when figuring out how much rope is needed to surround the field? A. yd B. yd2 C. yd3
a because u are trying to find the lengths and then just adding it to the widths. You don't need area so b is wrong, you are just simply adding so a is the right answer.
