Priya decomposed a square into 16 smaller, equal-size squares and then cut out 4 of the small squares and attached them around the outside of original square to make a new figure.

How does the area of her new figure compare with that of the original square?

• The area of the new figure is greater.

• The two figures have the same area.

• The area of the original square is greater.

• We don’t know because neither the side length nor the area of the original square is known.

___is the number of square units that covers a two-dimensional region, without any gaps or overlaps.

The area of region A is __ square units

The area of region B is __ square units. (decimal)

__ means “put together.” We use this word to describe putting more than one figure together to make a new shape.

__ means “take apart.” We use this word to describe taking a figure apart to make more than one new shape.
