Answer:

a) parallelogram

b) 18 square units

c) 19.21 units

d) see below

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

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
