What is the difference between the area of the large triangle and the area of the small triangle? 7.5 cm2 15.0 cm2 19.5 cm2 39.0 cm2

C. 19.5 cm5

Step-by-step explanation:

The small triangle's height is 6cm and the width is 2 cm.

Multiply them both to get 12cm.

Since it is half of the full model we will divide by 2.    12 ÷2=6.

For the bigger model, the width is 3cm, and the  height is 9cm.

3cm x 9cm = 27cm.

Since it is half of a full triangle, we half to divide by 2.

27 ÷ 2 = 13.5

HOPE THIS HELPS :)
