Answer:

Rs 100x² + 150x - 100

Explanation:

Area of the parking space = Length * Width

Area of the space = (2x-1)(x+2)

Expand

Area of the space = 2x² + 4x - x - 2

Area of the space = (2x²+3x - 2) sq. m

Since 1sq.m = Rs 50'

(2x²+3x - 2) sq. m= z

z = 50 (2x²+3x - 2)

z = 100x² + 150x - 100

hence the cost of the parking spsce is Rs.100x² + 150x - 100
