what is the perimeter and area of the right triangle one leg is 42mi and the other leg is 40mi
Find hypotenuse using Pythagorean theorem:
Let h = hypotenuse
then
h^2 = 42^2 + 40^2
h^2 = 1764 + 1600
h^2 = 3364
h = 58 miles
.
perimeter = 58 + 42 + 40 = 140 miles
area = (1/2)(42)(40) = 840 square miles
