Answer:
5. P = 23 m
A = 15 
6. P = 24.4 in
A = 15.3 
Step-by-step explanation:
Area formula of a triangle is A = 1/2 bh
Area formula of a parallelogram is A = bh
5. The height of a triangle is perpendicular to the base.
A = 1/2 * 10 * 3
A = 15 
6. The height of the parallelogram is also perpendicular to the base.
A = 9 * 1.7
A = 15.3 
Perimeter means you add all the side lengths.
5. The side lengths are 5m, 8m, and 10m. Adding those together, you get 23m.
6. A parallelogram has congruent opposite sides. That means your side lengths are 9 in, 3.2 in, 9 in and 3.2 in. Adding those together, you get 24.4 in.
Multiples: 15, 30, 45, 60, 75. 5/80 or 1/16

I am assuming you mean as a whole number, since that fraction can't be simplified down. 20 goes into 100 5 times, so we need to multiply 9 x 5. That gives us 45 and 100, or the new fraction 45/100. 45/100 is equal to 0.45
Side XZ needs to be congruent to side AC. The answer is D.
