Detailed Solution for RRB ALP & Technician Mock Test (English) - 17 - Question 4

Ratio of sides = 13 : 14 : 15
Perimeter of triangle = 168 cm
Let the sides are 13x, 14x, and 15x
∴ 13x + 14x + 15x = 168
⇒ 42x = 168
⇒ x = 4
∴ sides are 13 x 4 = 52 cm
14 x 4 = 56 cm
15 x 4 = 60 cm
s = sum of sides/2 = 168/2 = 84


Let BL be altitude on the largest side AC of  ABC
Area of Δ ABC = 1344 cm2
⇒ 1/2 x base x altitude = 1344 cm2

⇒ 30 BL = 1344
⇒ BL = 1344/30 = 44.8 cm
