Answer:
30 in
Explanation:
If the scale drawing has a base length of 10 in whe the real object has a base length of 25 inches, the scale of the drawing is 1:25
(25 divided by 2.5 = 10)
Since you already have the base length you need to find the height of the scale drawing. The height of the real object is 15 in so the scale drawing would be 6 in.
(15/2.5 = 6)
Now use the formula A= b x h/2 to find the area of the scale drawing.
A = 10 x 6/2
A = 60/2
A= 30
