Question

In the triangle below, if AC = 21 m, CP =18 m, and AB = 20 m, find the area of the triangle ABC.

Answer 1

We can find the area as follows:

`\begin{gathered} A=(1)/(2)bh \\ where: \\ b=AB=20 \\ h=CP=18 \\ so: \\ A=(1)/(2)(20)(18) \\ A=(360)/(2) \\ A=180m^2 \end{gathered}`

Answer:

b. 180 m^2
