If the length of a rectangle is twice its width and it has a perimeter of 48, then the rectangle is 16 in length and 8 in width.
Length = (Perimeter - twice width) / 2
Because the perimeter is lenght + length +width +width, you do perimeter - double the width, and then halve the remaining number. that should give you the length.
by appying 2l+2w
Perimeter is Length + width x 2 or Length + length + width + width. This is perimeter for any shape including a rectangle. Perimeter of a rectangle is all sides added together for a rectangle.
Perimeter = 2*(L + W).
Subtract two times the length from the perimeter and divide the remainder by two. This should be the width.
The length of the rectangle is 18cm. The width of the rectangle is 9cm.
The length of a rectangle is twice its width. If the perimeter of the rectangle is , find its area.
The length of a rectangle is 8 inches. The width of the rectangle is 4 inches. What is the perimeter of the rectangle in inches?
the length of a rectangle is 5 more then the width. Find the perimeter and the area of the rectangle
perimeter = 2 x (length + width) ⇒ length + width = perimeter ÷ 2 ⇒ length = (perimeter ÷ 2) - width So to find the length of the given rectangle, subtract the width from half the perimeter is how to do it. IF you meant "What is the length..." then: length = perimeter ÷ 2 - width = 40 ÷ 2 - 2 in = 20 - 2 in = 18 in
The perimeter of a rectangle is the distance around the rectangle. The area of a rectangle is the space inside the rectangle. To calculate either one you need the length and the width of the rectangle. To calculate the area multiply the length times the width. To calculate the perimeter add the length+width+length+width (that is the distance all the way around)
Multiply length by width
By forming a quadratic equation from the information given and then the length and width can be found by solving the equation.
If the given dimensions are the length and width of a rectangle then its perimeter is 15.6+4.5+15.6+4.5 = 40.2
The perimeter of a rectangle with a length of 8.5 feet and a width of 4.5 feet is 26.
If the shape is a rectangle, then Perimeter = 2(Length + Width) So Width = Perimeter/2 - Length
Perimeter = 2 * width + 2 * length, so rearranging --> width = (Perimeter / 2) - length
Length + length + width + width = perimeter. Length + width x 2 = perimeter
The perimeter of a rectangle is double the (sum of length plus width).
perimeter = (2*length) + (2*width) length = 2*width so perimeter = (2*2*width) + 2*width = 6*width perimeter = 48 so you can figure out the width and length
you need length and width length multiply width = area length + length + width + width = perimeter
