Dimensions of a rectangle is 72 inches by 24 inches - how many square feet are in the rectangle?
12 square feet.
If the width of the rectangle is 3 inches what is the area?

When you fold a square paper vertically the new rectangle has a perimeter of 39 inches what is the original area of the square?
When a square paper is folded vertically to form a rectangle with a perimeter of 39 inches, the length of the rectangle is 19.5 inches (half of the perimeter). Since the length of the rectangle is the same as the side length of the original square, the area of the original square can be calculated as the square of the side length, which is 19.5 inches squared, equaling 380.25 square inches.
What is the area of a rectangle with a length of 12 inches and a width of 7 inches?
Area = Length * Width = 12*7 = 84 square inches.
If the area of a rectangle is 40 square inches and the length is 6 inches more than the width what is the length and the width of the rectangle?
(6 + w) = length w = width (6 + w)(w) = 40 square inches w squared + 6w = 40 w = 4 inches and the length must be equal to 10 inches
