The perimeter of an isosceles triangle is 26 cm while equal sides together measure 20 cm. The third side and each of the equal sides are respectively.

A) 6 cm and 10 cm
B) 8 cm and 9 cm
C) 10 cm and 8 cm
D) 14 cm and 6 cm

Correct Answer:

A) 6 cm and 10 cm

Description for Correct answer:
Let the third side be x.

According to the question

x + 20 = 26

=> x = 26 - 20 = 6 cm

Therefore, Each equal side = \( \Large \frac{20}{2} \) = 10 cm
