You can find the perimiter and area by first finding the length of the sides. You automatically know that one side is 12ft long, and you can find the other side by solving for 15-(6+6) = x. Then, to find the area, you would add 12 + x, and multiply 12 * x for the perimiter. Following this, you would get p= 30 and a= 15, therefore the answer is A
