Answer:
Triangle a- 24
Triangle b- 30
Triangle c- 70
Explanation:
To solve these three problems, we need to know the formula for finding the Area of a Triangle.
Area of a Triangle formula- 1/2x B (base) x H (height)
a.) First multiply the base and the height. In this case, the base and the height would be 12 and 4. Multiply 12 and 4.
12x4=48
Now, divide 48 by 2.
48/2=24
The area of triangle a is 24
b.) Multiply the base and the height. The base and the height would be 5 and 12. 4. Multiply 5 and 12.
5x12=60
Now, divide 60 by 2.
60/2=30
The area of triangle b is 30
c.) Multiply the base and the height. The base and the height would be 14 and 10. Multiply 14 and 10.
14x10=140
Now, divide 140 by 2.
140/2=70
The area of triangle a is 70
