Answer:The total area for the parallelogram-shaped tiles Felix needs to buy exists 80cm² at the price of $40.
Explanation:
What is meant by the area of parallelogram?
In calculating the area of a parallelogram, the base exists multiplied by the height, in an exact way as computing the area of a rectangle.
Given that, the base of one parallelogram-shaped tile exists 4cm with a height of 2 cm.
Area of one parallelogram shaped tile = 4cm × 2cm
Area of one parallelogram-shaped tile = 8cm²
Total area for the 5black and 5white tiles = 10 × 8cm²
Total area for the 5black and 5white tiles = 80cm²
Therefore, Felix must buy a total area of 80cm² of 10 parallelogram-shaped tiles.
