area of large triangle = 1/2 bh =1/2(5)(9) = 45/2 = 22.5
area of small triangle = 1/2 bh = 1/2(2)(6) = 12/2 = 6

the difference between the area of the large triangle and the area of the small triangle
=
22.5 - 6 = 16.5
answer
16.5 cm2

I LOVE the name of the logo creator, just saying ;)

A small = 1/2(2)(6) = 6 cm^2
A large = 1/2(5)(9) = 22.5 cm^2

Difference is 22.5 - 6 = 16.5 or C
