The perimeter is AB + BC + AC.

 

BC  =  AK + KB  =  6 + 8  =  14

 

Since AK is an altitude, triangle(ABK) is a right triangle. 

Its bases are AK = 6 and KB = 8.

To find AB, use the Pythagoren Theorem:  AB2  =  AK2 + KB2  =  62 + 82

Complete this equation to find the value of AB.

 

Also, triangle(AKC) is a right triangle.

Its bases are KC = 6 and AK = 6.

To find AC:  AC2  =  KC2 + AK2  =  62 + 62

Complete this equation to find the value of AC.

 

Now, use:  AB + BC + AC to find the perimeter.
