Question

find the area of the triangle below. be sure to include the correct unit in your answer. 6 cm (with right angle symbol) 19 cm 13 cm

Explanation:

Step1: Recall triangle area formula

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

Step2: Identify base and height

From the diagram, the base can be 13 cm and the corresponding height is 6 cm (since the dashed line with the right angle is the height relative to base 13 cm).

Step3: Calculate the area

Substitute base = 13 cm and height = 6 cm into the formula: $A = \frac{1}{2} \times 13 \times 6$. First, calculate $13 \times 6 = 78$, then $\frac{1}{2} \times 78 = 39$.

Answer:

39 square centimeters
