Question

consider this figure. enter the total area, in square feet, of the triangle.

Explanation:

Step1: Find the base of the triangle

The base of the triangle is the sum of the two - given lengths along the bottom, so $b = 8+2=10$ feet.

Step2: Recall the area formula for a 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. Here, $h = 2.4$ feet and $b = 10$ feet.

Step3: Calculate the area

Substitute the values into the formula: $A=\frac{1}{2}\times10\times2.4$. First, $\frac{1}{2}\times10 = 5$, then $5\times2.4=12$ square feet.

Answer:

12
