Question

the area of each triangle

Explanation:

Step1: Recall triangle - 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: For the first triangle

The base $b = 3.2$ in and the height $h = 5$ in. Substitute into the formula: $A_1=\frac{1}{2}\times3.2\times5$. First, calculate $3.2\times5 = 16$, then $\frac{1}{2}\times16=8$ square - inches.

Step3: For the second triangle

The base $b = 2.2$ and the height $h = 5.4$. Substitute into the formula: $A_2=\frac{1}{2}\times2.2\times5.4$. First, $2.2\times5.4 = 11.88$, then $\frac{1}{2}\times11.88 = 5.94$ square - units.

Answer:

The area of the first triangle is 8 square inches and the area of the second triangle is 5.94 square units.
