Question

Construct a triangle ABC whose perimeter is 14cm and sides are in the ratio of 2:3:4 .

Answer 1

Let the side =2x, 3x and 4x
Perimeter of the triangle =side+side +side
2x+3x+4x=9x
Given perimeter is=14
9x=14
X=14/9
X=1.55
Hence 1st side =(2×1.55)=3.10
2nd side =(3×1.55)=4.65
3rd side =(4×1.55) =6.2
