The perimeter of a parallelogram is 46in. If the length of one side is 14in., what is the length of a side adjacent to it?

1 answer:

6 0

Adjacent means connected to so you are looking for the width.

Perimeter = 2(length) + 2(width)
P = 2l + 2w

46 = 2l + 2w
l = 14

46 = 2(14) + 2w
46 = 28 + 2w
18 = 2w
9 = w

Width: 9 inches
