Eduardwww [97]

Answer:

28 ft


Step-by-step explanation:

Let longer side of rectangle be L and the shorter side be  S, thus we can write the ratio:

\frac{L}{S}=\frac{4}{3}


<em>Now putting 21 into S, we solve for L:</em>

\frac{L}{21}=\frac{4}{3}\\3L=4*21\\3L=84\\L=\frac{84}{3}=28


Hence, length of longer side is 28 ft.

8 x 30 : 5 x 30

If you do this, you'll end up with the ratio:

240 : 150
