Question

Find the perimeter of a right triangle whose sides containing the right angle are 6cm and 8cm. What is the perimeter of the triangle

Answer 1

Answer:

Perimeter of the triangle is 24cm.

Explanation :

We know that,

Perimeter of a triangle = a + b + c

[ a, b, and c denotes all sides ]

Where,

• a = 6cm.
• b = 8cm.
• c = ?

Let's find out the value of c.

Since, it's a right angled triangle.

By Pythagoras theorem.

→ c² = a² + b²

Substitute the value of a and b.

→ c² = 6² + 8²

→ c² = 36 + 64

→ c² = 100

→ c = √100

→ c = 10cm.

Therefore, the third side is 10cm.

So,

Perimeter of the triangle = 6cm + 8cm + 10cm.

= 24cm.
