Question

sides of a triangle are in the ratio 12 : 17 : 25 and its perimeter is 54 cm. Find its area.​

Answer 1

1/2 × base × height

Step-by-step explanation:

let the sides of the triangle be 12x,17x and 25x.

Therefore, 12x+17x+25x = 54

54x = 54

x = 1

therefore sides are 12,17 and 25cm

therefore area is equal to

1/2×12×17

=102 square cm
