Question

The perimeter of a right angled triangle is 56 cm and area 84cm, find the length of all sides of the triangle.​

Answer 1

Answer is
1/2+56+84
=98

Answer 2

Step-by-step explanation:

Perimeter of triangle = 56 cm

Semi perimeter = 56/2 = 28 cm.

Area of triangle = 84 cm²

R × S = 84

R = 84/28

R = 3 cm.

In a right angled triangle ,

R = Semi perimeter - Hypotenuse

3 = 28 - Hypotenuse

Hypotenuse = 28 - 3

Hypotenuse = 25 cm.
