Question

what is the area of the triangle? 9 yd. 12 yd. 10 yd. square yards submit

Explanation:

Step1: Recall the area formula for a triangle

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

Step2: Identify the base and height

From the diagram, the base of the triangle is \( 10 \) yards and the corresponding height is \( 9 \) yards.

Step3: Substitute the values into the formula

Substitute \( base = 10 \) and \( height=9 \) into the formula: \( A=\frac{1}{2}\times10\times9 \).
First, calculate \( 10\times9 = 90 \), then \( \frac{1}{2}\times90=45 \).

Answer:

45
