score: 7.5/21 answered: 8/21 question 9 find the area of the triangle pictured above. round your answer to the nearest tenth question help: worked example 1 post to forum

Explanation:

Step1: Recall the area formula for a triangle

The formula for the area of a triangle is $A = \frac{1}{2} \times base \times height$.

Step2: Identify the base and height

From the diagram, the base of the triangle is $6$ and the height is $6$.

Step3: Substitute the values into the formula

Substitute $base = 6$ and $height = 6$ into the formula: $A=\frac{1}{2}\times6\times6$.

Step4: Calculate the area

First, calculate $6\times6 = 36$, then $\frac{1}{2}\times36 = 18$. Since $18$ is already a whole number, when rounded to the nearest tenth, it remains $18.0$.

Answer:

$18.0$
