Question

find the perimeter of triangle whose three sides are 5cm and 7cm 6cm​

Answer 1

Answer:

18cm

Step-by-step explanation:

5 + 7 + 6 =18

Answer 2

Answer:

$\large\boxed{\sf{18\;cm}}$

Step-by-step explanation:

Given a triangle ∆ABC .

The side lengths of the sides are :-

• AB = 5 cm
• BC = 7 cm
• CA = 6 cm

Now, to find the perimeter.

We know that, perimeter is the total length of all sides.

Therefore, we will get,

=> Perimeter = AB + BC + CA

=> Perimeter = (5 + 7 + 6) cm

=> Perimeter = 18 cm

Hence, the perimeter of triangle = 18 cm.

• Perimeter of square = 4(side)
• Perimeter of rectangle = 2(length+Breadth)
