Question

The three sides are 4:3:4 if the perimeter of triangle is 55 CM find the each side

Answer 1

we consider the ratios as A,B,C

A=4x,B=3x,C=4x

perimeter of a triangle=55cm

FORMULA-p=a+b+c

4x+3x+4x=55

11x=55

x=55/11

x=5

A=4x=4(5)=20

B=3x=3(5)=15

C=4x=4(5)=20

and we can

say it is a isoscles triangle because two of its sides are equal
