54 square feet
To find the area of the completed flag, we need to use the formula for the area of a triangle:
Area = 0.5 * base * height
From the scale drawing on the left, we can see that the base of the triangle is 6 feet and the height is 18 feet.
Area = 0.5 * 6 * 18
Area = 54 square feet
Therefore, the area of the completed flag in square feet is 54.
Archer is sewing a triangular flag. He starts with the scale drawing on the left and plans to enlarge the flag to match the picture on the right. What will be the area of the completed flag in square feet? Use the formula sheet provided.
