Question

if the ratio of the sides of a triangle is 2:3:4 and the shortest side is 4 cm ,find the length of the other two sides.

Answer 1

Kk, if I say there is a 2:5 ratio of red pencils to blue pencils and there are 15 blue pencils, then there must be 6 red, because 15 is 3 x 5, so we must do 3 x 2.

 

We have a ratio of 2:3:4. Since the shortest side is 4, it must go in the place of the smallest number, 2 in this case.

 

Since 4 is double 2, we must double the other numbers.

 

The other two sides are 6 and 8.

 

Hope this helps!

Answer 2

let the sides of the triangle be 2A, 3A and 4A,

now according to the question, we have

2A=4,

A=2,


hence

1st side=4 cm,

2nd side=3a=3×2=6 cm,

3rd side=4a=4×2=8 cm
