Answer 7

The regular pentagon breaks up into 5 identical triangles (all of the triangles have the same area). Calculate the area of one triangle, then multiply by 5 to get the area of the pentagon.

Area of triangle = 0.5*base*height

Answer 8

thats correct

Answer 9

what da answer

Answer 10

If the base is 22.3 and height is 15.4, whats the area of the triangle?

Answer 11

7.7 times 5 equals 38.5

Answer 12

not sure how you're getting those numbers

Answer 13

you should use 22.3 and 15.4

Answer 14

oh ok

Answer 15

Its 858.55

Answer 16

The area of one triangle is
0.5*b*h
0.5*22.3*15.4
171.71

So the area of five of the triangles is 5*171.71 = 858.55
which is the area of the pentagon. You have the correct answer
