Mario’s Restaurant is planning to tile the floor of their outdoor dining area, represented by the composite figure below. The tile costs $1.50 per square foot. How much should the restaurant plan to spend on tile to complete the job?

Cost of tiling the floor of the restaurant = $346.5

Step-by-step explanation:

Since Mario's restaurant is in the shape of a composite figure.

Area of the composite figure = Area of the rectangle + Area of trapezoid

Area of the rectangle = 3 × 9

                                    = 27 square feet

Area of the trapezoid =

Here and are the parallel sides of the trapezoid and 'h' is the distance between these sides.

Area of the trapezoid =

                                    = 17 × 12

                                    = 204 square feet

Total area of the floor = 27 + 204

                                     = 231 square feet

Cost of the tiles = $1.5 per square feet

Total Cost of tiling the floor of Mario's restaurant will be,

= per square feet cost × Area of the floor

= 1.50 × 231

= $346.5
