First, let's find the scale factor used by Magnolia to create her drawing.
Scale factor = Actual length / Length on scale drawing
Scale factor = 25 inches / 10 inches
Scale factor = 2.5
Now, to find the height of Magnolia's scale drawing:
Height of scale drawing = Actual height / Scale factor
Height of scale drawing = 15 inches / 2.5
Height of scale drawing = 6 inches
Now that we have the dimensions of Magnolia's scale drawing (base length = 10 inches, height = 6 inches), we can find the area of the scale drawing.
Area = (1/2) * base length * height
Area = (1/2) * 10 inches * 6 inches
Area = 30 square inches
Therefore, the area of Magnolia's scale drawing is 30 square inches.
