the length of a rectangle is 1 cm less than twice its width. the area is 28 cm squared. find the dimensions of the rectangle.

Just translate the English into "math"

"the length of a rectangle is 1 cm less than twice its width"

l=2w-1

"the area is 28"

w(2w-1) = 28

solve as a quadratic.

Hint: it factors very nicely
