Question

The size of triangle are in ratio 5:12:13 and its perimeter 150m

Answer 1

let sides are 5x, 12x, 13x

××××××××××××××

Perimeter => sum of all sides
150 = 5x + 12x + 13x
150 = 30x
150/30 = x
5 = x

××××××××××××××××
Sides are :

5(5)=25
12(5)=60
13(5)=65

Answer 2

Heya !!!



Ratio of the sides of a triangle is 5:12:13.


Let X be common multiple to this ratio.



Then the all three sides becomes 5X , 12X and 13X .




Given that,


Perimeter of triangle = 150 m




5X + 12X + 13X = 150



30X = 150


X = 150/30


X = 5 m


Therefore,


side of triangle = 5X , 12X and 13X


=> 5 × 5, 12 × 5 and 13 × 5


=> 25 , 60 and 65m
