The area of a rectangle is 28 ft^2, and the length of the rectangle is 1ft more than double the width. Find the dimensions of the rectangle.
Answer provided by our tutors
area = width * length
let 'x' represent the width, then '2x+1' represents the length
28 = x*(2x+1)

x={3.5,-4}
The width is the positive value, 3.5.
3*(3.5)+1=8
The dimensions of the rectangle is 3.5 x 8 feet.
