Question

question 16 of 25
what is the area of a triangle with a base of 7 units and a height of 11 units?

a. 154 sq. units

b. 38.5 sq. units

c. 19.25 sq. units

d. 77 sq. units

Explanation:

Step1: Recall the formula for the area of a triangle.

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

Step2: Substitute the given values into the formula.

Here, the base \( b = 7 \) units and the height \( h = 11 \) units. Substituting these values into the formula, we get:
\( A = \frac{1}{2} \times 7 \times 11 \)

Step3: Perform the calculation.

First, multiply 7 and 11: \( 7 \times 11 = 77 \). Then, multiply the result by \( \frac{1}{2} \): \( \frac{1}{2} \times 77 = 38.5 \).

Answer:

B. 38.5 sq. units
