Question

Two sides of an isosceles triangle are each 2 cm more than the thrice the third Sid if the perimeter of an triangle is 67 cm find the length

Answer 1

let the third side be of x cm

so 67=x + (x+2) + (x+2)

so 67=3x + 4
so 63=3x
x=63/3 =21cm

so third side is 21cm
while the other two sides are 23cm each
