Answer:
28.80
Step-by-step explanation:
I took the test on edge 2020
5/15
16.6
A = 120, P = 55
Triangle
Area = (bh)/2
A = (20x12)/2
A =240/2
A = 120
Perimeter = a + b + c
to find c, use a^2 +b^2 = c^2
20^2 + 12^2 = c^2
400 + 144 = c^2
544 = c^2
c = about 23
20 + 12 + 23 = 55
The answer to this question is and always will be 0.
