L + W = 11 so L = 11 - W; L = 2W + 2;
so 11 - W = 2W + 2
add W to each side: 11 = 3W + 2
subtract 2 from each side: 9 = 3W
divide each side by 3: W = 3 so L = 8 m
Perimeter of a rectangle = twice (length + width), in this case 22 m.
12 meters
To calculate the perimeter of a rectangle one adds twice the width and twice the length... in this case (2 x 3 metres) + (2 x 7 metres) = 6 metres + 14 metres = 20 metres.
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
Area is length times width, perimeter is twice the sum of length and breadth.
The perimeter of a rectangle is 42. Meters. The length of the rectangle is threemeter less than twice the width.Mar
Perimeter of a rectangle = twice (length + width), in this case 22 m.
12 meters
The width of the rectangle is 13 meters. The perimeter of the rectangle is 50 meters, and its length is 12 meters. The 50 meters is 2 times the length plus 2 times the width. With a length of 12 meters, twice that is 24 meters. That leaves 50 meters - 24 meters for twice the width. And 50 - 24 = 26, which is twice the width. The 26 meters divided by 2 = 13 meters, which is the width of the rectangle.
The length of a rectangle is twice its width. If the perimeter of the rectangle is , find its area.
To calculate the perimeter of a rectangle one adds twice the width and twice the length... in this case (2 x 3 metres) + (2 x 7 metres) = 6 metres + 14 metres = 20 metres.

Area is length times width, perimeter is twice the sum of length and breadth.
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.)
For a rectangle, calculate twice the length, plus twice the width.For a rectangle, calculate twice the length, plus twice the width.For a rectangle, calculate twice the length, plus twice the width.For a rectangle, calculate twice the length, plus twice the width.
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.
Length = (Perimeter - twice width) / 2
