Question 13 of 20: Select the best answer for the question. 13. If a triangle has a height of 12 inches and a base of 5 inches, what's its area? A. 90 sq. in. B. 45 sq. in. C. 30 sq. in. D. 60 sq. in.
Solution
The area of a triangle is calculated by the formula: 1/2 * base * height.
Step 1: Identify the base and the height from the question. The base is 5 inches and the height is 12 inches.
Step 2: Substitute the base and height values into the formula. So, Area = 1/2 * 5 inches * 12 inches.
Step 3: Calculate the area. Area = 1/2 * 60 sq. inches = 30 sq. inches.
So, the correct answer is C. 30 sq. in.
