Answer:
10.5 units^2
Explanation:
The formula for a triangle is 1/2 * b * h
Count the units for the base of the triangle - 7
Count the units for the height - 3
Use formula: 1/2 * 7 * 3
= 10.5
Note: When countung the units, count the sides you definitely know the units for. If you use any other areas of the triangle as the base, you'll end up getting a height that isn't very exact.
