A rectangular courtyard is shown in the diagram below. The shaded portion represents grass, and the rectangles A and B are cement pads for picnic tables and chairs. The area of pad A is twice the area of pad B. The remaining area is grass, which has an area of 2,040 square feet.
(The picture is a rectangle with a big box which is A and a littler box B. the left side of the box is 40 ft and the bottom is 60 ft.)
1. If x represents the area on pad B, write an equation which includes the areas of the entire figure. Explain your reasoning.
2. What is the area of each cement pad? show all work.
3. If the pads were the same size, how would their areas change?

Please help??
