Question

Bablu has three sticks of lengths 3, 4 and 5 cm. Ramesh has three sticks of lengths 3, 5 and 9 cm. How many triangles can Bablu and Ramesh make with their sticks? With explaination plz

Answer 1

Answer:

Bablu can make 1 triangle while, Ramesh can make 0 triangles.

Step-by-step explanation:

The sum of any two sides of a triangle is greater than the third side.

Given that,

Bablu has three sticks of lengths = 3cm, 4cm and 5cm

Ramesh has three sticks of length = 3cm,5cm and 9cm

Bablu:

• 3cm + 4cm > 5cm

      = 7cm > 5cm

• 4cm + 5cm > 3cm

      = 9cm > 3cm

• 5cm +3cm > 4cm

      = 8cm > 4cm

Ramesh:

• 3cm + 5cm < 9cm

      = 8cm < 9cm

• 5cm + 9cm > 3cm

      = 14cm < 3cm

• 9cm + 3cm > 5cm

      = 12cm > 5cm

here in Ramesh's calculation you can see the sum of two sides is lesser than the third side..

∴ Bablu can make 1 triangle while Ramesh can make none.
