What is a poygon for a square?

A polygon is a two-dimensional geometric figure with straight sides. A square is a specific type of polygon known as a quadrilateral, which has four equal sides and four right angles. In general, polygons can have any number of sides, but a square's defining characteristics make it a regular polygon, as all its sides and angles are equal.

A square room has area 16 m2. What is the perimeter of the room?

To find the perimeter of a square room with an area of 16 m², we first determine the length of one side. Since the area of a square is given by the formula ( \text{Area} = \text{side}^2 ), we can calculate the side length as ( \sqrt{16} = 4 ) m. The perimeter of a square is calculated using the formula ( \text{Perimeter} = 4 \times \text{side} ), which equals ( 4 \times 4 = 16 ) m. Thus, the perimeter of the room is 16 meters.

How much of an acre is 140 feet by 180 feet?

To find the area of a rectangle in acres, first calculate the area in square feet: 140 feet × 180 feet = 25,200 square feet. Since 1 acre is equal to 43,560 square feet, you can convert the area to acres by dividing: 25,200 square feet ÷ 43,560 square feet/acre ≈ 0.578 acres. Therefore, a space measuring 140 feet by 180 feet is approximately 0.578 acres.

How many acres is 70 feet x 120 feet?

To find the area in acres of a rectangular space measuring 70 feet by 120 feet, first calculate the area in square feet: 70 feet × 120 feet = 8,400 square feet. Since one acre is equivalent to 43,560 square feet, you can convert the area to acres by dividing: 8,400 square feet ÷ 43,560 square feet per acre ≈ 0.193 acres. Thus, 70 feet by 120 feet is approximately 0.193 acres.

How many 1x6x12 covers 182 square feet?

To determine how many 1x6x12 boards are needed to cover 182 square feet, first calculate the area of one board. A 1x6 board (which is actually 0.75 inches by 5.5 inches) has an area of 0.75 ft x 5.5 ft = 4.125 square feet. Next, divide the total area by the area of one board: 182 sq ft ÷ 4.125 sq ft/board ≈ 44.1. Therefore, you would need approximately 45 boards to cover 182 square feet, rounding up since you can't use a fraction of a board.

How many square meters in one Lot of land?

If two rectangles have the same perimetre they must have the same area?

No, two rectangles with the same perimeter do not necessarily have the same area. The area of a rectangle is calculated as length multiplied by width, while the perimeter is the sum of all sides. For example, a rectangle with dimensions 2x5 (perimeter 14) has an area of 10, while a rectangle with dimensions 3x4 (also perimeter 14) has an area of 12. Thus, rectangles can have the same perimeter but different areas.
