Sal is tiling his entryway. the floor plan is drawn on a unit grid. each unit length represents 1 foot. tile costs $2.25 per square foot. how much will sal pay to tile his entryway?

To find the area, we divide the shape into two parts at approximately the middle line. The top shape is a trapezoid of base length 7 feet and height 6 feet, while the bottom shape is a parallelogram with one side equal to 4 feet.

Area of trapezoid = (7 + 4)/2 x 6
Area of trapezoid = 33 sq ft

Area of parallelogram = 4 x 4
Area of parallelogram = 16 sq ft

Total area = 49 sq ft

Cost = 2.25 x 49
Cost = $110.25
