Answer:
Width = 6 cm.
Step-by-step explanation:
The formula for are is length x width. You have the length, which is 12. This gives you this equation...
12 x ? = 72 cm.
If you use the inverse operation (opposite) of multiplication, you divide both sides by 12, giving you 6 cm. To double check, do 6 x 12, which equals 72.
