    three of its sides. If the length of the unpainted side is 9 ft, and the sum of the lengths of the painted sides is 37 ft, then what is the area of the parking space in square feet?
    A 126 ft² Correct Answer Incorrect Answer
    B 81 ft² Correct Answer Incorrect Answer
    C 252 ft² Correct Answer Incorrect Answer
    D 46 ft² Correct Answer Incorrect Answer

    Solution

    The one of sides of the rectangle = 9 ft. The sum of the remaining three sides = 37 ft. The sum of the remaining two sides = 37-9 = 28 ft. The length of the other side of rectangle = 28/2 = 14 ft. So, the length and breadth of the rectangle are 14 ft. and 9 ft. respectively. Area of rectangle = 14 x 9 = 126 ft².
