                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
