Question

two equal sides of a triangle are each 4m less than three times the third side find the dimensions of the triangle if its perimeter is 55 m

Answer 1

let the 3rd side of triangle be xm

accordig to the condition,

1st side=2nd side=3x-4

perimter of triangle=sum of all 3side =55

3x-4+3x-4+x=55

7x-8=55

7x=63

x=63/6=9

1st side=2nd side=3*9-4

=27-4

=23m

3rd side=9m
