The scale factor is 10/25 = 2/5. This means that every dimension on the scale drawing is 2/5 of the actual dimension.
The height of the scale drawing is 2/5 of 15 inches, which is 6 inches.
The base length of the scale drawing is 2/5 of 25 inches, which is 10 inches.
To find the area of the scale drawing, we need to multiply the height by the base length and divide by 2 (since it's a triangle).
Area of scale drawing = (6 inches * 10 inches) / 2 = 30 square inches
To find the actual area of the triangle, we use the actual dimensions:
Actual area = (15 inches * 25 inches) / 2 = 187.5 square inches
So Magnolia's scale drawing has an area of 30 square inches, but the actual area of the flag is 187.5 square inches.
