Question

from unit 1, lesson 8 find the area of the shaded triangle. show your reasoning.

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: Identify base and height

The base of the shaded triangle is $b = 6$ and the height is $h=(2 + 4)=6$.

Step3: Calculate the area

Substitute $b = 6$ and $h = 6$ into the formula: $A=\frac{1}{2}\times6\times6$.
$A=\frac{1}{2}\times36 = 18$.

Answer:

18
