What can be the perimeter of a rectangle made up of 6 squares with an area of 49 cm2?

1. By the statement of the problem, it is known that the rectangle is composed of six squares, the area of each is 49 cm².

2. We know that the area of a square is equal to the product of its two dimensions, so the side is calculated as √49 cm² = 7 cm.

The resulting rectangle has one side 7 cm * 6 = 42 cm, and the second is 7 cm.

Then the perimeter P is obtained as the doubled sum of its two sides, that is

P = 2 * (42 cm + 7 cm) = 2 * 49 cm = 98 cm.

Answer: The perimeter of the composed rectangle is 98 centimeters.
