To find the area of the completed flag, we need to find the scale factor of the enlargement first.
Looking at the two scale drawings, we can see that the length of the base of the flag has been doubled in the enlarged version. Therefore, the scale factor of enlargement is 2.
Next, we need to find the area of the original triangle. The original triangle has a base of 6 units and a height of 5 units. Therefore, the area of the original triangle is:
Area = 1/2 * base * height
Area = 1/2 * 6 * 5
Area = 15 square units
Now, since the scale factor of enlargement is 2, the area of the completed flag will be:
Area of completed flag = (2^2) * Area of original flag
Area of completed flag = 4 * 15
Area of completed flag = 60 square units
Therefore, the area of the completed flag will be 60 square units.
