The hypotenuse of a right-angled triangle is 65 cm and its base is 60 cm. Find the length of perpendicular and the area of the triangle.

Answer :

Given: Base = 60 cm


Hypotenuse = 65 cm



We know that,


Base2 + Perpendicular2 = Hypotenuse2


602 + Perpendicular2 = 652


Perpendicular2 = 652 - 602


Perpendicular2 = 4225– 3600


Perpendicular2 = 625 cm2


Perpendicular = 25 cm


Area of a triangle = 1/2 × Base × Height


= 1/2 × 60 cm × 25 cm


= 750 cm2
