Single portion of a tennis court is 27 ft wide and 78 ft long show worka) what is the lengthb) what is the area in m squaredc) if a serve is measured at 185 km/h how many seconds does it take to travel the length of the courtd) how many literally of paint are needed to paint the court of 1 gal of paint covers 150 ft squared

A) 24 m; B) 2.0 × 10^2 m^2; C) 0.46 s; D) 53 L

Part A) Length of court

Length = 78 ft × (12 in/1 ft) × (1 m/39.37 in) = 24 m

Part B) Area of court

Width = 27 ft × (12 in/1 ft) × (1 m/39.37 in) = 8.23 m

A = lw = 24 m × 8.23 m = 2.0 × 10^2 m^2

Part C) Time of serve

Time = 24 m × 1 km/1000 m × 1 h/185 km × 3600 s/1 h = 0.46 s

Part D) Volume of paint

A = lw = 78 ft × 27 ft = 2100 ft^2

V = 2100 ft^2 × (1 gal/150 ft^2) × (3.785 L/1 gal) = 53 L
