If the length of a rectangle is 6 cm longer than twice the width and that the perimeter of the rectangle is 108 cm then what is the width and the length?

Suppose the width is w cm
Then length is 2w + 6 cm
So, the perimeter is 2l + 2w = 2*(2w + 6) + 2w = 4w + 12 + 2w = 6w + 12
Thus 6w + 12 = 108 so that 6w = 96 and then w = 16 cm
And then, l = 2w + 6 = 32 + 6 = 38 cm

What is the perimeter of a rectangle with a length of 12.1 in and a width of 4.6 in?
The perimeter of a rectangle is twice the sum of the width and length: perimeter = 2 x (4.6in + 12.1 in) = 33.4 in
If the length of a rectangle is 3 cm longer than twice the width and that the perimeter of the rectangle is 90 cm then what is the width and the length?
the width equals 14 cm. and the length equals 31 cm.
Area and perimeter of a rectangle?
Area is length times width, perimeter is twice the sum of length and breadth.
How does increasing the dimensions of a rectangle impact the perimeter?
If you increase the rectangle's length by a value, its perimeter increases by twice that value. If you increase the rectangle's width by a value, its perimeter increases by twice that value. (A rectangle is defined by its length and width, and opposite sides of a rectangle are the same length. The lines always meet at their endpoints at 90° angles.)
What is the area of a rectangle that its perimeter is 39?
156 It is impossible to calculate the area of a rectangle from its perimeter if no other dimension is known. The area of a rectangle is the product of its length and width, and the perimeter is twice the sum of its length and width.
The length of a rectangle is twice its width If the perimeter of the rectangle is 54y find its area?
The length of a rectangle is twice its width. If the perimeter of the rectangle is , find its area.

What is the formula to find the length of a rectangle when the perimeter and width is already given?
Length = (Perimeter - twice width) / 2
Perimeter of a rectangle 4 meters by 7 meters?
Perimeter of a rectangle = twice (length + width), in this case 22 m.
What is the expression of a perimeter of a rectangle if a rectangle has a width of n and a length of 2n?
The perimeter of any rectangle is twice the sum of the length and the width of the rectangle; in the present instance, 2(n + 2n) = 6n.
