Question

find the area of a triangle whose height is 10 in. and whose base is 11 in. enter an exact number. learn it: find the area of a plane geometric figure.

Explanation:

Step1: Recall 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: Substitute values

Given $b = 11$ in and $h=10$ in, we substitute into the formula: $A=\frac{1}{2}\times11\times10$.

Step3: Calculate

$A=\frac{1}{2}\times11\times10 = 55$ in².

Answer:

55 in²
