Rick used a stick to trace a large rectangle in a sandy lot near his house. The rectangle measures 13 feet by 15
feet. What is the perimeter of the rectangle?

56 feet

Step-by-step explanation:

Perimeter is what the sum of all sides lengths of a polygon is. So if the retangle measures 13x15 feet, the perimeter would be 13+13+15+15. Because the 13x15 is only two sides, and a retangle has 4 sides. So we need to incorperate the other two sides, which are the same as the others because it is a retangle.

Hope this helps!

56

Step-by-step explanation:

P = 2(L + W)

L =15

W = 13

P = 2 ( 15 + 13)

P = 2 (28)

P = 56
