A triangular flag has a height of 15inches and a base length of 25 inches. Magnolia makes a scale drawing of the flag in which the base length is 10 inches. What is the area of magnolia's scale drawing?
The scale factor from the original flag to Magnolia's drawing is 10/25 = 2/5. This means that all lengths in Magnolia's drawing are 2/5 of the corresponding lengths in the original flag.
The height of Magnolia's drawing is (2/5) x 15 inches = 6 inches.
The area of Magnolia's drawing is:
(1/2) x base x height = (1/2) x 10 inches x 6 inches = 30 square inches.
Therefore, the area of Magnolia's scale drawing is 30 square inches.
