Answer:
c
Step-by-step explanation:
Synthetic division yields
..... || 2 2 -12 1 6
-3 || -6 12 0 -3
= = = = = = = = = = = = = =
..... || 2 -4 0 1 3
which translates to

Make the length x+4 and the width x and then make a formula x(x+4)=21
then u ll get x^2+4x-21=0 and then solve for x ..... the width is 3
