Conversion formula: 240 inches = 240 / 12 = 20 feet
Let the length be x-12 and the width be x: 2(length+width) = perimeter 2(x-12+x) = 240 2x-24+2x = 240 4x = 240+24 4x = 264 x = 66 Therefore: length = 54 feet and width = 66 feet
Ah, what a delightful question! To find the square footage of a rectangle, you simply multiply the length by the width. In this case, 12 feet multiplied by 20 feet equals 240 square feet. Just imagine all the happy little feet that can dance around in that space!
12' x 20' = 240 square feet
105 / 9 = 11.6 recurring - that is 11.6666... or 11 and two thirds.
