    1. Find each perimeter.
      1.  

        A rectangle with sides of length 2.3cm and 8.6cm.

      2.  

        A triangle with sides of length 8mm, 9.3mm, and 3.8mm.

      3.  

        A triangle with sides of length 4.8in, 16.11in, and 17.23in.

      4.  

        A four sided parallelogram with short sides of length 0.12m and long sides of length 0.31m.

      5.  

        A triangle with sides of the following lengths: 7.2m, 8.3m, and 12.4m.

    2. Find the area for the following: 
      1.  

        A rectangle with width 8m and height 2m

      2.  

        A rectangle with width 4.1in and height 2.3in.

      3.  

        A square with 1 mm sides.

      4.  

        A triangle with base 8cm and height 3cm.

      5.  

        A triangle with base 9in and height 4in.

      6.  

        A parallelogram with base 20cm and height 9cm.

      7.  

        A trapezoid with bottom base 15 mm, top base 7 mm, and height 8 mm.

    3. Find the area for the following figures below:
      1.  

        A four-sided polygon with left side length 0.04ft, bottom length 0.095ft, top length 0.04ft, and a diagonal that connects the top to the bottom that measures 0.07ft. It can be visualized as a square connected to a triangle..

      2.  

        A five sided polygon with a rectangular shape that has a triangle cut out of it. The left and right sides of the rectangular base are 4.9 in. The bottom is 10.2 in. The triangular cutout has a height of 1.8 in with a base of 10.2 in.

      3.  

        A polygon with eight sides. It is not an octagon, but can be visualized as one large square with two  smaller rectangles connected to it.

    4. Find the area of the shaded region.

      A rectangle with a rectangle cut out of the inside. The inside rectangle has a width of 4.83in and a height of 1.61in. The outside rectangle has a width of 5.21in and a height of 1.74in.
