find the perimeter and area of a right triangle if the shortest side is 20m and the longest side is 29m. Include correct units with your solution.

Steve,
since the hypotenuse is the longest side, the other leg, of length x can be found by:
20^2 + x^2 = 29^2
x = 21
so, the perimeter is 20+21+29 = 70
the area is 20*21/2 = 210
