Question

Sides of a triangle are in the ratio of €12:17:25 and its perimeter is 540 find its area

The ratio of side of triangle = a:b:c
12:17:25

If perimeter of triangle = 540 cm

12x + 17x +25x = 540 cm
54x = 540 cm
X = 540÷54
X= 10

1st side of triangle = 12×10=120
2nd side of triangle = 17×10=170
3rd side of triangle = 25×10=250

Half perimeter of triangle = side
540÷2 = 270 cm
Area of triangle = S(s-
