The length of a dance floor to be replaced is 1 foot shorter than twice than width. you measured the width to be 12.25 feet. what is the area and what is the most accurate area you can report?

287.875 square feet.

Step-by-step explanation:

Let x be the width ( in feet ) of the dance floor,

∵ the length of a dance floor to be replaced is 1 foot shorter than twice than width.

So, the length of the dance floor = 2x - 1

According to the question,

x = 12.25 ft,

⇒ 2x - 1 = 2(12.25) -1 = 23.5 ft,

Thus, the area of the floor = length × width

= 23.5 × 12.25

= 287.875 square feet.
