Question

Find the area and perimeter for each polygon.

Answer 1

Answer:

5. P = 23 m

   A =  15 $m^{2}$

6. P = 24.4 in

   A = 15.3 $in^{2}$

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 $m^{2}$

6. The height of the parallelogram is also perpendicular to the base.

    A = 9 * 1.7

    A = 15.3 $in^{2}$

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.
