Answer 1

The length of two sides of the triangle are 12 cm and 14cm. Perimeter of the triangle is 36 cm. What is the length of the 3rd side?

Hope it helps...

Answer 2

Answer:

Let the third side be x cm

perimeter of triangle=Sum of all sides

So,

36 cm =12cm +14cm+x

36cm =26 cm+x

36cm-26cm=x

10cm =x

Hence the length of third side is 10 cm
