First find the area of the trapezium    get the average of the bases  (10 and 16)   and multiply by the height

   (10+16)/2  *  7.6 =  98.8 m2

 

How many liters of paint are required?    98.8 m2 / 1.9 m2/l = 52 liters

 

The cans of paint are 5 liters each      How many cans ?     52 liters / 5 liters/can = 10.4 cans        round up to 11 cans

 

11 cans   *   L16.99/can =   L  186.89    to buy all of the paint necessary
