The perimeter of an isosceles triangle is 30 cm . The length of each congruent side is 3cm more than the length of its base. Find the lengths of all the sides.

Let the congruent sides of an isosceles △ be x. Let the base of the isosceles △ be y According to the 1st condition, x + x + y = 3 0 2 x + y = 3 0 According to the 2nd condition x = y + 3 x − y = 3 Solving equation (1) and (2) 2 x + y = 3 0 x − y = 3 ------------------- 3 x = 3 3 x = 3 3 3 ​ x = 1 1 By substituting x = 1 1 in equation (1) 2 x + y = 3 0 2 ( 1 1 ) + y = 3 0 2 2 + y = 3 0 y = 3 0 − 2 2 = 8 ∴ The length of the sides of a △ are 1 1 c m , 1 1 c m and 8 c m.
