Side ‘ab’ denotes the hypotenuse. Now, let us solve a few examples to understand the application of the above mentioned concepts. For the given triangle, find the area. In this case, we are given the measurements of two sides and one extended side making another right angle triangle. If we can find the height of the triangle, then we will be able to calculate the area of the same. Using Pythagorean Theorem, we can find the measurement of height. 5 2 = 3 2 + h 2 h 2 = 25 – 9 = 16 h = 4 Now, the area can be calculated by the formula, A = ½*b*h Area = ½ * 7*4 = 14 unit 2 Let us consider another example. Consider the given triangle and find its perimeter and area.
