Answer 1

The width of a rectangle is 1 units less than the length. The area of the rectangle is 20 units. What is the width, in units, of the rectangle?

L*(L-1)*h=20

20/h/L=(L-1) or w.

Answer 2

a = l * w

given a = 20

w = l-1

20 = l*(l-1)

20=l²-l

l²-l-20=0

(l+4)(l-5)

Now we know the length is 5 and the width is 4
