You left out two sides of the rectangle. The perimeter is P = 2l + 2w = 90 cm. It still doesn't fit.

I believe that the length is 25 cm and the width is 20 cm.

The perimeter is 70 cm. Yours is 90 cm.

 August 14th, 2018, 12:41 AM #7 Global Moderator   Joined: Dec 2006 Posts: 19,722 Thanks: 1806 The frame's perimeter is 90 cm, whereas the photo's perimeter is 70 cm, so the frame is suitable (if the photo's length is less than the length of the frame). Thanks from topsquark

You don't seem to understand the answers given. It MIGHT fit, depending on the dimensions, not just the total perimeter.

What do you mean by the dimensions?
