What is a rectangle? How do you calculate the area and the perimeter of a rectangle?EMEE_ said:
But you know that the ratio of the length to the width is 3/2, or ##\frac L W = \frac 3 2##. From this equation you can write the length in terms of the width.EMEE_ said:
The formula for finding the perimeter of a rectangle is 2(length + width). This means that you need to add the length and width of the rectangle together, and then multiply that sum by 2.
If you only know the length of the rectangle, you can still find the perimeter by doubling the length and adding it to itself. This is because a rectangle has two pairs of equal sides, so doubling the length will give you the total length of all four sides.
No, the perimeter of a rectangle cannot be a negative number. Perimeter is a measure of distance and distance cannot be negative. If you get a negative number when calculating the perimeter, you have likely made a mistake in your calculations.
The perimeter of a rectangle is not directly related to its area. However, you can use the perimeter to help you find the area of a rectangle. For example, if you know the perimeter and one of the sides of a rectangle, you can use the formula A = P/4 - s to find the area.
Yes, it is possible for the perimeter of a rectangle to be equal to its area. This occurs when the rectangle is a square, as a square has four equal sides. In this case, the perimeter would be equal to 4 times the length of one side, which is also the area of the square.
