Find the area of a triangle whose height is 23 centimeters and base length is 16 centimeters.

We’re looking for the area of a triangle. The formula for finding the area of a triangle equals one-half times ℎ times 𝑏, where ℎ is the height and 𝑏 is the base of the triangle. We’ll start with this formula and then we’ll plug in the information that we know.

We know that the height is 23 centimeters. We’ll bring down the one-half, plug in 23 centimeters for ℎ. We’re also given that the base is 16 centimeters, so that will be plugged in for 𝑏. And then we multiply one-half times 23 times 16. Those values multiplied together to equal 184. We’re also dealing with area, which means we’ve multiplied centimeters times centimeters. That means our units will be centimeters squared.

The area of a triangle whose height is 23 and base length is 16 is 184 centimeters squared.
