Question from BJ, a student: The perimeter of a rectangular field is yards. If the length of the field is yards, what is its width? |
Hi,
I didn't receive any numbers but that's not important. The perimeter is the distance around the rectangle, in other words
perimeter = length + width + length + width.
Hence half the perimeter is the length plus the width. Thus divide the perimeter by 2 and then subtract the length to find the width.
