Question

The perimeter of a triangular sail is 44 feet. One side of the sail measures 18 feet and the second side measures 11 feet. What is the length of the third side?

Answer 1

Answer: The length of third side is 15.

Explanation:

Alright, lets get started.

Please refer the diagram I have attached.

The perimeter of given triangle is 44.

One side, suppose a is 18.

Second side, suppose b is 11.

Suppose, third side is c.

So the perimeter will be :

`18+11+c=44`

`29+c=44`

Subtracting 29 in both sides

`29+c-29=44-29`

`c=15`

Hence the length of third side is 15. Answer

Hope it will help :)
