Question

find the area of the triangle.
5.5 cm
6 cm
□ cm²

Explanation:

Step1: Recall triangle area formula

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

Step2: Identify base and height

From the diagram, the base ($b$) is $5.5$ cm and the height ($h$) is $6$ cm.

Step3: Substitute into formula

Substitute $b = 5.5$ and $h = 6$ into the formula: $A = \frac{1}{2} \times 5.5 \times 6$.
First, calculate $5.5 \times 6 = 33$. Then, $\frac{1}{2} \times 33 = 16.5$.

Answer:

$16.5$
