C = 0.35s + 9.95
c = 0.35(35) + 9.95
c = 12.25 + 9.95
c = 22.20 <== cost of 35 songs

The sides of the rectangle are aligned with the coordinate axes, so the dimensions of the rectangle are easily determined to be 4 -(-7) = 11 units by 1 -(-1) = 2 units. As with any rectangle, the area is the product of length and width.
The area is 11*2 = 22 square units.
