Two sides of a triangle are 12 cm and 14 cm. The perimeter of the tria

1.	Two sides of a triangle are 12 cm and 14 cm. The perimeter of the triangle is 36 cm. What is the third side?
Answer» Let the length of third side be x cm. Length of other two side are 12 cm and 14 cm. Now, Perimeter of triangle = 36 cm ⇒ 12 + 14 + x = 36 ⇒ 26 + x = 36 ⇒ x = 36 - 26 ⇒ x = 10 cm Thus, the length of third side is 10 cm.

Two sides of a triangle are 12 cm and 14 cm. The perimeter of the triangle is 36 cm. What is the third side?

Answer»

Let the length of third side be x cm.

Length of other two side are 12 cm and 14 cm.

Now, Perimeter of triangle = 36 cm

⇒ 12 + 14 + x = 36

⇒ 26 + x = 36

⇒ x = 36 - 26

⇒ x = 10 cm

Thus, the length of third side is 10 cm.
