Question

the perimeter of a triangle is 600 M if the ratio of its side is 12 ratio 13 ratio 15 then find the longest side

Answer 1

Hey dear!!


Here is yr answer....


Given,

Perimeter of triangle = 600m

ratio of its side = 12:13:15


Method l :
^^^^^^^^^^



Now,

sum of the ratios = 12+13+15 = 40


1st side = 12/40 × 600 = 180m

2nd side = 13/40 × 600 = 195m

3rd side = 15/40 × 600 = 225m


Therefore, the longest side 15 = 225



Method ll :
^^^^^^^^^^


ratio of sides = 12:13:15

Suppose the sides are 12x, 13x, 15x


Perimeter of rectangle = sum of all sides


12x+13x+15x = 600

40x = 600

x = 600/40

x = 15



1st side = 12(x)

= 12(15)

= 180m


2nd side = 13(x)

= 13(15)

= 195m


3rd side = 15(x)

= 15(15)

= 225m


Therefore, the longest side 15 = 225


Hope it hlpz.....
