A right triangle has side lengths of 12 inches and 13 inches

A right triangle has side lengths of 12 inches and 13 inches. If you add a half inch boarder around the perimeter of the triangle, what are the new side lengths?

Solution

Right triangle : a= 12 inch ; b = 13 inch

Add 0.5 inch on both ends of each side: 0.5 +12+0.5 = 13

Add 0.5 inch on both ends of each side: 0.5 +13+0.5 = 14

So, new lengths are 13 inches and 14 inches
