Copy the following figures onto your paper. Then find the area and perimeter of each shape. Assume that all corners are right angles. Show all work. Homework Help ✎

  1. Shape

    To find the area, separate the shape into two boxes, find the area of the two sections, and then add them together for the total area.

    16 x 12 = 192
    13 x 35 = 455
    area = 192 + 455

    area = 647 units2

    To find the perimeter (the distance around a shape) add up all of the sides of the shape.

    perimeter = 16 + 12 + 19 + 13 + 35 + 25

    perimeter = 120 units
