Question

A pentagon is formed by connecting the tips of a starfish's leds, as shown below

what is the area of the Pentagon.​

Answer 1

71.5

Explanation:

You have to break it down into 3 different triangles. The area formula for a triangle is A = 1/2 * b * h.

Triangle 1: A = 1/2 * 10 * 4 = 20

Triangle 2: A = 1/2 * 11 * 5 = 27.5

Triangle 3: A = 1/2 * 6 * 8 = 24

Now add all your totals together, 20+27.5+24 = 71.5
