There is a rectangular table. It is 6 feet long and 3 feet wide. The area of a tablecloth is twice the area of the tabletop. When it is laid on the tabletop, the length of each side is the same. How much is the length and width of the tablecloth? The accuracy is 0.1 feet

Let X be the same length of each side
∴3×6＝2×﹙3﹢x﹚x﹢2×﹙6﹢x﹚x
X = (- 9 ± 3 √ 17) / 4 = 0.8423 (rounding off negative roots)
∴ 2x=1.7
The length and width of the tablecloth are 7.7 feet and 4.7 feet respectively

There is a rectangular table, 6 meters long and 3 meters wide. The area of a tablecloth is twice that of the tabletop. When it is laid on it, the length of each side is the same. If the length of each side is x meters, the equation is______ ．

Let the length of the drop be x, then (6 + 2x) × (3 + 2x) = 2 × 6 × 3, so the answer is: (6 + 2x) × (3 + 2x) = 36

If the length of a rectangular board is reduced by 4 decimeters, its area will be reduced by 24 square decimeters. At this time, the remaining part is just a square. How many square decimeters is the original rectangular area?

Rectangle's width: 24 △ 4 = 6 (decimeter), rectangle's length: 6 + 4 = 10 (decimeter), rectangle's area: 10 × 6 = 60 (square decimeter); answer: original rectangle's area is 60 square decimeter

After removing 6 decimeters from the length, the area will be reduced by 24 square decimeters. How many decimeters is the width of the rectangle

Part of the reduced area is 6cm long and part is wide. According to the area formula of the rectangle, it is found that 24 / 6 = 4decimeter, that is, the width of the rectangle

There is a rectangular table. It is 6 feet long and 3 feet wide. The area of a tablecloth is twice the area of the tabletop. When it is laid on the tabletop, the length of each side is the same. How much is the length and width of the tablecloth? The accuracy is 0.1 feet
