Given :

A right angle triangle ABC .

To Find :

The perimeter of ABC .

Solution :

Since, triangle ABC is right angled and angle ∠ABC is 46° .

So, AC = AB cos 46° = 7.64 units.

Also, CB = AB sin 46° = 7.91 units.

Therefore, the perimeter of ΔABC is :

P = 11 + 7.64 + 7.91 units

P = 26.55 units

Hence, this is the required solution.
