Answer:
[tex]\$ 80[/tex]
Step-by-step explanation:
Since we know the price per square meter, we can find area of the figure and multiply it by the price per square meter.
The area of the composite figure consists of a trapezoid and a rectangle.
Area of trapezoid: [tex]\frac{(8+4)}{2}\cdot 2=6\cdot 2 = 12\:\mathrm{m^2}[/tex]
Area of rectangle: [tex]4\cdot 2=8\:\mathrm{m^2}[/tex]
Therefore, the area of the composite figure is equal to [tex]12+8=\boxed{20\:\mathrm{m^2}}[/tex]. Since the problem states that it will cost Anthony $4 per square meter, the total cost to tile the entire figure will be [tex]20\cdot 4=\boxed{\$80}[/tex]
