The area of the triangle is 58.9 square cm
How to determine the triangle area?
The attached triangle complete the question
Start by calculating the base of the triangle using the following Pythagoras theorem
Base^2 = b^2 - a^2
So, we have:
Base^2 = 20^2 - 19^2
Evaluate
Base^2 = 39
Take the square roots
Base = 6.2
The area is then calculated as:
Area = 0.5 * Base * Height
Where
Height = a = 19
So, we have:
Area = 0.5 * 6.2 * 19
Evaluate
Area = 58.9
Hence, the area of the triangle is 58.9 square cm
