Question

if x = 13 units and h = 4 units, then what is the area of the triangle shown above?
a. 78 square units
b. 26 square units
c. 52 square units
d. 8 square units

Explanation:

Step1: Recall area formula for triangle

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

Step2: Substitute given values

Given $x = 13$ units and $h=4$ units. Substitute into the formula: $A=\frac{1}{2}\times13\times4$.

Step3: Calculate the area

First, $13\times4 = 52$, then $\frac{1}{2}\times52=26$ square - units.

Answer:

B. 26 square units
