6) Write a function named computeArea where it takes in 3 inputs, 2 double and 1 String. The two double represents the dimension and the String represents the shape of the object. Luckily, we only want to know the areas of basic shapes such as: triangle, rectangle, square, and circle. For the string input, the circle must be case insensitive. Ie. computeArea(1, 1, "SQuaRe"); => 1 computeArea(1, 1, \"CiRcLe\"); => 3.14 computeArea(1, 2, \"TrianGle"); => 1
