Question

a right triangle has a height of 20 centimeters and a base of 10 centimeters. what is the area of the triangle? cm²

Explanation:

Step1: Recall area formula

The area formula for a triangle is $A=\frac{1}{2}bh$, where $b$ is the base and $h$ is the height.

Step2: Substitute values

Given $b = 10$ cm and $h=20$ cm, we substitute into the formula: $A=\frac{1}{2}\times10\times20$.

Step3: Calculate result

$\frac{1}{2}\times10\times20 = 100$ $cm^{2}$.

Answer:

100
