Question

what is the area? 15 cm 16.5 cm square centimeters

Explanation:

Step1: Recall triangle area formula

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

Step2: Identify base and height

In this right - triangle, the base $b = 16.5$ cm and the height $h = 15$ cm.

Step3: Substitute values into the formula

Substitute $b = 16.5$ and $h = 15$ into the formula $A=\frac{1}{2}\times b\times h$. So $A=\frac{1}{2}\times16.5\times15$.
First, calculate $16.5\times15 = 247.5$. Then, $\frac{1}{2}\times247.5=123.75$.

Answer:

123.75
