You are planting a square garden. each side is 8 feet long. you use a square section in the center that has sides of 4 feet long. you divide the remaining area into 4 equal sections. what is the area of each remaining section?

  12 square feet

Step-by-step explanation:

The area of a square is the square of its side length.

The area of the whole garden is (8 ft)² = 64 ft².

The area of the center section is (4 ft)² = 16 ft².

The remaining area is ...

  64 ft² - 16 ft² = 48 ft²

One fourth of that area is ...

  (48 ft²)/4 = 12 ft²

Each of the 4 equal sections is 12 square feet.

58 stamps is the number she gets each week. So if she went for one week, 58*1=58. 58*2=116 and so on. Because we don't know the exact number of weeks, we say 58w or 58*w because you multiply however many number of weeks she collects.
