Question

Find the ratio between one side of the triangle in the photograph to one side of the triangle in the actual drawing.

• A. $1in:50ft$
• B. $15in:1ft$
• C. $1in:15ft$
• D. $1in:75ft$

Answer 1

The correct option is A $1in:50ft$


Length of one side of traingle in actual drawing = 750 ft.
Length of one side of triangle in photograph = 15 in.

∴ Length of one side of traingle which is 1 inch in photograph is:

$\frac{750\times 1}{15}=50ft.$

So, the scale is:
$1in:50ft$
