Question

A sheet of paper measures 30 cm by 2 cm. A strip 5 cm wide is cut from it all around. Find the area of the remaining sheet and the strip cut out.

Answer 1

I think you need to proofread what you posted. This doesn't make sense.

Answer 2

How do you get it "5 cm wide... cut from all around" when it only measures 2 cm in one direction?

As far as I can tell:

The area cut would be 5*2 = 10 cm^2

The remaining area would b3 25*2 = 50 cm^2

Answer 3

I suspect it was 30 by 20 to start with.
