Question

Area of right angled triangle, if the radius of its circum circle is 5 cm and altitude drawn to hypotenuse is 4 cm, will be

Answer 1

Using Pythagorean Triplet •~
AB^2=BC^2+CA^2
4^2=5^2+CA^2
CA^2=25-16
CA=√9=3cm
Therefore the sides are 5cm,3cm and 4cm.

Area of the triangle will be:―
$1 \div 2 \times base \times height = 5 \times 3 \div 2 = 7.5$
YOUR ANS is 7.5 cm^2
