Detailed Solution
Download Solution PDFGiven:
ratio of sides of a triangle = 5 : 4 : 3
perimeter of the triangle = 84 cm
Formula used:
Perimeter of triangle = Sum of sides
Calculations:
Let the sides of triangle be 5x, 4x and 3x so that they are in ratio 5 : 4 : 3.
∴ 5x + 4x + 3x = 84
⇒ 12x = 84
⇒ x = 7 cm
So, the sides of triangles are 35, 28 and 21 meters.
∴ The length of the largest side is 35 m.
