There is a right triangle named ABC. If AB=2 yards and BC=6 yards, what is the perimeter of triangle ABC?
A) 4*square root of 2 yards
B) 8 yards
C) 8 + 2*square root of 10
D) 8 + 2*square root of 14
E) 28 yards
well, if the right angle is at B
hypotenuse = sqrt(2^2+6^2) = 2 sqrt 10
then perimeter = 8+2 sqrt 10
