Question

Construct a triangle ABC whose perimeter is 14.4 cm and sides are in the ratio of 2:3:4 .

Answer 1

let the side of triangle=2x,3x,4x
Sol.= we know that the perimeter of triangle= sum of all side
so 2x+3x+4x=14.4
9x=14.4
x=14.4/9
x=1.6
So side of triangle are
2x=2×1.6=3.2
3x=3×1.6=4.8
4x=4×1.6=6.4

know u can construct a triangle
