The formula for finding the area of a rectcngle is: L * W = A
Let x represent the width and 2x represent the length (twice the width). Set up the equation and solve:
2x * x = 50 (then simplify)
2x² = 50 (then divide both sides to find the value of x²)
x² = 25 (then find the square root of 25 to solve for x)
x = 5
the width (x) = 5, and the length (2x) = 10
Let the length be 2x and the width be x: length*width = area 2x*x = 50 2x2 = 50 x2 = 25 x = 5 feet

Length of garden = 2 times its width plus 5 feet Let 2x+5 = length and let x = width Area of sidewalk = 6x = 213 square feet x = 35.5 feet which is the width of the garden 2*35.5+5 = 76 feet which is the length of the garden
The width is 6 cm and the length is 12 cm.
The diameter is twice the length of radius, so it is 28 feet.
A = area, L = length, W = width A = LW L = 2W A = (2W)W = 2W2 2W2 = 50 W = 5 ft
4Improved Answer:-30 feet of fencing will be needed
Let the length be 2x and the width be x: length*width = area 2x*x = 50 2x2 = 50 x2 = 25 x = 5 feet
A farmer wants to fence a rectangular garden whose perimeter is 60 yards. The length of the garden exceeds twice the width by 6 yards. What are the length and width of the garden?
If the perimeter is 84 feet and the length is twice the width, then the length will be 28 feet and the width will be 14 feet.
$90If the area of the garden is 50 ft2, then the area is represented by the formula50 = l * wIf the length is twice the width, then l = 2w, and50 = 2w * w ===> 50 = 2w2Solving for w, we getw = 5Now the perimeter of the fencing is 2w + 2(2w) = 6w, and with w = 5P = 6(5) = 30.If the fencing costs $3/ft, then we have$3/ft * 30 ft = $90
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.

Length of garden = 2 times its width plus 5 feet Let 2x+5 = length and let x = width Area of sidewalk = 6x = 213 square feet x = 35.5 feet which is the width of the garden 2*35.5+5 = 76 feet which is the length of the garden
Width = 16 feet Length = 38 feet
14 feet (14+14+28+28 = 84)
Area=Length * Width. if length =4 and width =5...area is 20. if doubled....(4*2)*(5*2)=A*4. When length and width double, area is multiplied by 4.
