1. Sabrina has designed a rectangular painting that measures 50 ft in length and 40 feet in width. Alfed has also designed a rectangular painting, but it measures x feet on each side. When x=3, what is the area of Alfred's painting?
2. A rectangular swimming pool is 20 feet long and 10 feet wide. It is surrounded by a fence that is x feet from each side of the pool. Write a expressions for the length, width, and area of the fenced region.
3. Circle A has a radius of (x+4) units. A large circle, B has radius of (x+5) units. use the formula A = π × r`2 to write an expression for the difference in the areas of the circles. leave your answer in terms of PI. then use 3.14 for PI to approximate to the nearest whole number the difference in the areas when x=10
4. This week Leo worded (x+4) hours at a pizzeria. He is paid (x-4) dollars per hour. Leo's friend Frankie worked the same # of hours, but he is paid (x-2) dollars per hour. Write an expression for the total amount paid to the two workers. Then find the total amount if x = 12 dollars.
