Samantha is buliding a fence around her house. Her property is in the shape of a rectangle that measures 45 feet by 80 feet

You would need 250 feet of fence because:

45 x 2 (45 + 45) = 90 Because it is a rectangle and one of the other sides match.

80 x 2 (80 + 80) = 160 Same as above

160 + 90 to add each side group and your answer is 250
