Solution:
The image shows a worksheet with a rectangle that is divided into units to help calculate its area. The rectangle's dimensions are labeled in parts. One side is labeled as "2 units" and the other side is partially labeled with "2 units" plus an additional half unit (noted as "1/2 unit").To find the missing information and calculate the area, we will add the lengths of the sides together. The length is 2 units plus an additional half unit, which gives us 2.5 units. The width, clearly given, is 2 units.Now that we have both dimensions of the rectangle, we can calculate the area by multiplying the length by the width.The length of Emma's rectangle is 2.5 units, and the width is 2 units.Area = length × widthArea = 2.5 units × 2 unitsArea = 5 square unitsSo, the area of Emma's rectangle is 5 square units.
