a^{x} / a^{y} = a^{x-y}
W = (20r^{5}s^{7}t^{4}) / (4r^{2}s^{5}t^{2}) = (20/4) r^{5-2} s^{7-5} t^{4-2} =
5r^{3}s^{2}t^{2}
Since the area of a rectangle is related to it's length times width (A = L*W), then that formula can be rearranged to show that the width is the Area divided by the Length (W=A/L). So:
W = 20r5s7t4/4r2s5t2 (substitute the given expressions for A and L)
W = 20*5*7*4*r*s*t / 4*2*5*2*r*s*t (rearrange to make it easier to see that r, s, & t cancel)
W = 20*5*7*4 / 4*2*5*2 (rewrite after cancellation)
W = 35 (perform the division from above)
