Question

what is the area of the triangle? 10 mm 9 mm 8 mm square millimeters submit

Explanation:

Step1: Recall triangle area formula

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

Step2: Identify base and height

From the diagram, the base of the triangle is \( 8 \) mm and the height is \( 9 \) mm.

Step3: Substitute values into formula

Substitute base \( = 8 \) mm and height \( = 9 \) mm into the formula: \( A = \frac{1}{2} \times 8 \times 9 \).

Step4: Calculate the area

First, calculate \( 8 \times 9 = 72 \), then \( \frac{1}{2} \times 72 = 36 \).

Answer:

36
