if the length and height of the rectangle are 2x-3 and 5(-2), respectively, the perimeter and area of the rectangle are:
Perimeter = 2*lenght + 2*height
Perimeter = 2*(2x-3) + 2(5)(-2)
Perimeter = 4x - 6 - 20
Perimeter = 4x - 26
Area = length* height
Area = (2x - 3)*(5(-2))
Area = (2x - 3)*(-10)
Area = -20x + 30
