5-48.

Tina is going to put

If the frame is one tile wide, how many 1-inch-square tiles will she need?

To find the number of tiles, it may be useful to find the perimeter of the picture. Remember that the perimeter is the distance around something, so you will know how many tiles fit around the picture. If you use this strategy, do not forget to account for the corner tiles.A frame figure: The interior is divided into 4 rows of 7 tiles each.

You can also draw one inch square tiles with each side. This way you can count the tiles Tina needs. The frame figure has frame divided into 26 square tiles.

Would more 1-inch square tiles fit inside the frame or on the frame? Show how you know.
