First find the length of the missing side. Drop a perpendicular from the vertex connecting the lines with side 13 and the unknown side. The length of the sides are 12 and 9, and by Pythagoras' theorem, the hypotenuse is 15.
With that, the perimeter is 15 + 13 + 9 + 25 = 28 + 34 = 62.
The area is (13*9) + 1/2 (12)(9) = 117 + 54 = 171
62 * 3 = 186 > 171, answer is A.
With that, the perimeter is 15 + 13 + 9 + 25 = 28 + 34 = 62.
The area is (13*9) + 1/2 (12)(9) = 117 + 54 = 171
62 * 3 = 186 > 171, answer is A.
