First, we need to find the scale factor used by Magnolia in the scale drawing. We can do this by dividing the actual base length by the scaled base length:

Scale factor = Actual base length / Scaled base length
Scale factor = 25 inches / 10 inches
Scale factor = 2.5

Next, we can use the scale factor to find the scaled height of the flag:

Scaled height = Actual height / Scale factor
Scaled height = 15 inches / 2.5
Scaled height = 6 inches

Now that we have the scaled base length and height, we can find the area of Magnolia's scale drawing:

Area of scale drawing = 0.5 * Scaled base length * Scaled height
Area of scale drawing = 0.5 * 10 inches * 6 inches
Area of scale drawing = 30 square inches

Therefore, the area of Magnolia's scale drawing is 30 square inches.
Simply this

The area of Magnolia's scale drawing is 30 square inches.
