  • Question
  • How many squares with sides 1/2 inch long are needed to cover a rectangle that is 4 ft long and 4 ft wide ?


  • Options
  • A. 9216
  • B. 10246
  • C. 12345
  • D. 7527

  • Correct Answer
  • 9216 

    Explanation

    It takes four of those little squares -- each one 1/2 inch on a side -- to cover one square inch. That's because each one is 1/2 x 1/2, or 1/4 of a square inch.
    In a rectangle that is 48 inches by 48 inches, there are 2304 square inches.(1 ft = 12 inches)
    Since it takes 4 little squares to cover 1 sq inch, then it would need 2304 x 4 squares (1/2 inch on a side each) to cover a rectangle 4 feet by 4 feet.

    That is 9,216 of those squares.
