Question

Two equal sides of an isosceles triangle are each 2cm more than thrice the third side. If the perimeter of triangle is 67cm, find the length of its sides.

Answer 1

let the base of isosceles triangle be X
according to condition
other two equal side = 2 + 3X
perimeter of triangle = 2(2+3X ) +X
67 =4+6X+X
67-4 =7X
63/7 =X
therefor base is equal to 9 cm and other two equal side of isosceles triangle is equal to 29 CM
