question 23 of 25
what is the area of a triangle with a base of 7 units and a height of 11 units?
a. 19.25 sq. units
b. 38.5 sq. units
c. 77 sq. units
d. 154 sq. units

Explanation:

Step1: Recall area formula

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

Step2: Substitute values

Given $b = 7$ and $h=11$, we substitute into the formula: $A=\frac{1}{2}\times7\times11$.

Step3: Calculate result

$A=\frac{77}{2}=38.5$ square - units.

Answer:

B. 38.5 sq. units
