A picture frame is 20cm x 16cm. There is 192cm squared of picture showing. Find the width of the frame.

Hmmmm.

Well if the width subtracts from the original dimensions,
then

(20-2w)(16-2w)=192

solve for w.

• Algebra -

inside the perenthesis you have to subtract 2 from 20 you should get 18 and if you subtract 2 from 16 you should get 14.multiply 18x14 and you should get 192 and that's how you check your answer.
