Answer: The total cost to paint the mural will be $80.

First, we need to find the area of the trapezoid. The formula is one-half times the height times the sum of the bases.

0.5 x 6 (9 + 11) = 60 m^2

Each can will cover 12 m^2, so divide 60 by 12 to find that we need 5 cans.

The cost of each can is $16, so 5 x 16 = $60.
