Question

Find the area of right angled triangle if the dimeter of its circumference is 10cm and altitude drawer to the hypotenuse is 4.5 cm long

Answer 1

Diameter of circumcircle =10 cm.

Radius of circumcircle =5 cm.

let the hypotenuse be x cm.

2R=

$\frac{x}{sin90degrees}$

10=x/1

•°•x=10 cm.

Hypotenuse of the triangle is 10 centimetres.

Height of the triangle is 4.5 cm.

Area=4.5×10=45 cm²
