Question

lesson 7: triangles area of triangles find the area of a triangle with a base of 15 inches and a height of 6 inches. a. 90 inches b. 45 inches c. 45 inches squared d. 90 inches squared check answer

Explanation:

Step1: Recall the formula for the area of a triangle

The formula for the area of a triangle is $A = \frac{1}{2} \times base \times height$.

Step2: Substitute the given values into the formula

Here, the base is 15 inches and the height is 6 inches. So we substitute these values into the formula: $A = \frac{1}{2} \times 15 \times 6$.

Step3: Perform the calculation

First, calculate $15 \times 6 = 90$. Then, take half of that: $\frac{1}{2} \times 90 = 45$. The unit for area is square inches, so the area is 45 square inches.

Answer:

c. 45 inches squared
