Find the perimeter and area of the polygon shown below. The polygon is a trapezoid made up of a rectangle and a right triangle. The rectangle is 20 feet long and 15 feet wide. The right triangle joins the rectangle at a side that is 15 feet wide, and this is the height of the triangle. The base of the triangle is 8 feet and the hypotenuse is 17 feet.

Step 1
The perimeter is the sum of all sides. For the rectangle, we have two sides of 20 feet and two sides of 15 feet. For the triangle, we have one side of 8 feet and one side of 17 feet. So, the perimeter is 20+20+15+15+8+17 = 95 feet. Show more…
