How do you find the length of a rectangle with the area and length?
How do you find the length of a rectangle with the area and length?
Because a square has four sides of equal length, the area is given by A = L2. If you know the area, you can immediately determine the length of each side, because it’s the square root of the area. The length of each side of the square is the square root of 20, which is 4.47 meters.
How do you find length when given area and width?
For example, say the area is 12 square inches, and the width is 3 inches. The length can be found by 12/3 = 4 inches for the length. area = length x width therefore length = area /width.. Example: The area of a rectangle is 100 cm².
What is the formula in finding the length of a rectangle?
A = L * W, where A is the area, L is the length, W is the width or breadth. NOTE: When multiplying the length by the width, always ensure you work in the same unit of length. If they are given in different units, change them to the same unit. Let’s work out a few example problems about the area of a rectangle.
What is area of the rectangle?
In other words, the area of a rectangle is the product of its length and width. That is, A = l x w where l is the length and w is the width of the rectangle. For example, the area of a rectangle of length 35 m and width 25 m is 35 times 25 or 875 square meters. The area of the carpet is equal to the area of the room.
What is the formula of length?
Arc length formula is used to calculate the measure of the distance along the curved line making up the arc (a segment of a circle)….Formulas for Arc Length.
| Arc Length Formula (if θ is in degrees) | s = 2 π r (θ/360°) |
|---|---|
| Arc Length Formula (if θ is in radians) | s = ϴ × r |
| Arc Length Formula in Integral Form | s= ∫ba√1+(dydx)2dx |
What is the formula to find the area of a rectangle?
A = length × width = a × b A = length × width = a × b. In other words, the area of a rectangle is the product of its length and width. The perimeter is measured in units such as centimeters, meters, kilometers, inches, feet, yards, and miles.
What is the distance around a rectangle called?
The distance around a rectangle is called the perimeter of the rectangle. It is usually denoted by P P. To find the perimeter of rectangle we add the lengths of its sides. Thus, the perimeter of a rectangle with the length of a a and the width of b b is
How do you find the length of the diagonal of a rectangle?
If we know side lengths of the rectangle, it is easy to calculate the length of the diagonal using the Pythagorean Theorem. A diagonal divides a rectangle into two right triangles. By applying the Pythagorean Theorem to ΔABC Δ A B C, we get
How many square feet is a rectangular bedroom 12×15?
A rectangular bedroom with one wall being 15 feet long and the other being 12 feet long is simply 12 x 15 = 180 square feet. Since in multiplication the order in which the numbers are multiplied does not matter, you need not worry about switching the places of the two measurements.
