How do you divide area of a rectangle?

How do you divide area of a rectangle?

Divide the area by the length if you are given these two figures but not the width. For example, if a rectangle has an area of 20 square feet and a length of 10 feet, divide 20 by 10 to get a width of 2 feet. Multiply the length times 2 and subtract this figure from the perimeter, if you’re given these values.

How do you find the length and width of a rectangle if you know the area?

To calculate the length and width of a rectangle first, calculate the value of width ‘w’ by using the area of rectangle formula that is, ‘w = A/l’.

How do you find the length and width of a rectangle when given the perimeter?

In that case, we use the following formulas: If the perimeter and the length of a rectangle are known, the width can be calculated using the formula: Width = P/2 – l, where l = length of the rectangle; and w = width of the rectangle, and P = perimeter of the rectangle.

What is the sides of rectangle?

A Rectangle is a four sided-polygon, having all the internal angles equal to 90 degrees. The two sides at each corner or vertex, meet at right angles. The opposite sides of the rectangle are equal in length which makes it different from a square.

What is the width of rectangle?

To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides. This number divided by 2 is the width.

Is square a rectangle?

Yes, a square is a special type of rectangle because it possesses all the properties of a rectangle. Similar to a rectangle, a square has: interior angles which measure 90∘ each. opposite sides that are parallel and equal.

What is the unit of area of a rectangle?

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. The area is measured in units units such as square centimeters (cm2) ( c m 2), square meters (m2) ( m 2), square kilometers (km2) ( k m 2) etc.

How do you calculate square feet for a rectangle?

For example, a garden shaped as a rectangle with a length of 10 yards and width of 3 yards has an area of 10 x 3 = 30 square yards. 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.

How do you find the length and width of a rectangle?

where a a and b b are the length and width of the rectangle, respectively. Length of Diagonal of Rectangle Formula: The diagonal of a rectangle is determined by the following formula d = √a2 + b2 d = a 2 + b 2 where a a and b b are the length and width of the rectangle, respectively.

How to find the diagonal of a rectangle?

To find the diagonal using the same dimensions: Take the square root of both sides and the diagonal d is approximately 7.2 inches These examples illustrate how to calculate the area, perimeter, and diagonal of a rectangle manually, but if you prefer to use the calculator for quicker results or to merely check your work, then feel free to do so.
