Question

The perimeter of a triangle is 99cm . The length of its sides are in the ratio 2 : 3 : 4 . Find the length of its three sides . ​

Answer 1

Step-by-step explanation:

let the sides be 2x,3x and 4x. perimeter of triangle is 99 cm so 2x+3x+4x=99 so we got the value of x. now put the value of x in 2x 3x and 4x ang we will get sides

Answer 2

Given Side of triangle are in the ratio 2 : 3 : 4 and the perimeter is 99 cm.

Let x be the common multiple

So , Let the sides of the triangle be 2x , 3x , 4x

Perimeter = sum of all sides of triangle

But perimeter = 99cm

So , 99 = 2x + 3x + 4x

99 = 9x

x = 99 / 9

x = 11

So the three sides of the triangle are :

1. ) 2x = 2(11) = 22cm

2.) 3x = 3(11) = 33cm

3.) 4x = 4(11) = 44cm

I hope it helps u dear friend ^_^♡♡
