Question

The length of the sides of a triangle are in the ratio 3 : 5 : 6 and its perimeter is 154 cm. Find the area of a triangle.

Answer 1

Answer:

let the value of ratio be x

hence

3:5:6

= 3x,5x,6x

perimeter of a triangle = sum of all sides

154 = 3x +5x+6x

154 = 14x

x = 154 /14

x = 11

therefore

sides are : 3(11), 5(11) , 6(11)

= 33 ,55, 66cm
