To find the area of Lena's rug, we can use the formula for the area of a rectangle, which is length multiplied by width. In this case, the length is 3 meters and the width is 3/4 meters. So the area would be 3 meters times 3/4 meters. To calculate the area of Lena's rug, we multiply the length by the width. The length is 3 meters and the width is 3/4 meters. So the area would be 3 meters multiplied by 3/4 meters. 3 times 3 is 9, and 9 divided by 4 is 2.25. Therefore, the area of Lena's rug is 2.25 square meters.
