How do you use the scale on a scale drawing to find the measurements of actual projects

multiply the scale drawings side lengths by the scale

Step-by-step explanation:

for instance, if i have a square shaped scale drawing with the side lengths of 4in, and the scale is 2in, i would multiply 4 by 2, and the actual drawing's side lengths would be 6.

if i did not know the scale and i knew the actual drawings side lengths and the scale drawings side lengths, i would divide the corresponding lengths

example: rectangular scale drawing with the lengths, 5, 5, 10, and 10. and an actual drawing with the lengths 10, 10, 20, and 20. if i divide 20 by 10 or 10 by 5, i'd get 2, the scale
