In this case, we need to use the Area formula for a rectangle, and work backwards.

A=l%2Aw

From the given information, we have:

64=4%2Aw

Then just solve for w:

w=16

So the answer would be the width is equal to 16 cm.

To double check:

l%2Aw=4cm%2A16cm=64cm%5E2=A

Usually in practice, the length of a rectangle is longer than its width, but the concept is still the same.

I hope this helps!
