Hypotenuse of a right triangle has air points (2,7) and (11,-5). what is the perimeter of the triangle

Answer 1

hypotenuse = 15

(2,7) to (11,-5) is a distance of 15, the hypotenuse of a right triangle with sides

(7- -5) = 12 and ((11-2) = 9

h^2 = 12^2 + 9^2 = 144 + 81 = 225

h = sqr225 = 15

perimeter = 15+12+9 = 36
