Question

what is the area of the triangle? 15 mi. 8 mi. 18 mi. square miles

Explanation:

Step1: Recall area formula for triangle

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: Identify base and height

From the figure, the base $b = 15$ mi and the height $h=8$ mi.

Step3: Calculate the area

Substitute $b = 15$ and $h = 8$ into the formula: $A=\frac{1}{2}\times15\times8=\frac{1}{2}\times120 = 60$ square - miles.

Answer:

60 square miles
