    Answer:

      a) parallelogram

      b) 18 square units

      c) 19.21 units

      d) see below

      e) perimeter: 38.42 units; area: 72 square units

    Step-by-step explanation:

    a) The horizontal bases are the same length but the sides are not vertical, so the figure is a parallelogram.

    __

    b) The area is the product of base and height:

      A = bh = 6·3 = 18 . . . . square units

    __

    c) The lengths of the sides can be found from the Pythagorean theorem. Each has a rise of 3 and a run of 2, so its length is ...

      d = √(3²+2²) = √13 ≈ 3.606

    The total length of the four sides is ...

      P = 2(6 + 3.606) ≈ 19.21 . . . . units

    __

    d) See below

    __

    e) Since the dilation factor is 2, the perimeter is 2 times that of MATH, so is ...

      2P = 2×19.21 units = 38.42 units

    and the area is 2² = 4 times that of MATH, so is ...

      4A = 4×18 square units = 72 square units
