question 15 of 25
what is the area of the triangle shown below?
8
10
a. 40 sq. units
b. 9 sq. units
c. 18 sq. units
d. 80 sq. units

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 (the horizontal side) is 10 units and the height (the vertical side, perpendicular to the base) is 8 units.

Step3: Substitute into formula

Substitute base = 10 and height = 8 into the formula: $A = \frac{1}{2} \times 10 \times 8$.
First, calculate $10 \times 8 = 80$. Then, $\frac{1}{2} \times 80 = 40$.

Answer:

A. 40 sq. units
