Example Question #1 : Geometry
What is the area of the right triangle in the following figure?
In order to solve this problem, we need to recall the formula for area of a right triangle:
or
Now we can substitute in our side lengths from the question:.
Example Question #2 : Geometry
What is the volume of the rectangular prism in the following figure?
The formula used to find volume of a rectangular prism is as follows:
Substitute our side lengths:
Remember, volume is always written with cubic units because volume is how many cubic units can fit inside of a figure.
