The sum of the two right sides of a right triangle is 14 cm, and the area is 24 cm 2
Let the length of one right angle side be xcm, then the length of the other right angle side be (14-x) cm, 12 × x (14-x) = 24, the solution is X1 = 6, X2 = 8, when X1 = 6, 14-x = 8; when x2 = 8, 14-x = 6; answer: the length of two right angle sides are 6, 8
