Picture a circle, the length from one side to the next is 20. Now picture just the edges being cut off, the length from one side to next is still 20. Now you know the length is 20 and the area is 90
The formula to find the area of a rectangle is A = L(W)
90 = 20W (now divide 90/20)
the width is 4.5. The dimensions are 4.5 and 20
