Answer:
171
Step-by-step explanation:
Since the hypotenuse is the longest side on a right triangle, the other two sides would have to be less than 20. So, you would get the two numbers under 20, which are 19 and 18. In order to find the area of a right triangle you do A x B x 1/2. So you would do 18 x 19 x 1/2 which is 171.
