Answer: The wingspan is 36 m.
Using a proportion to solve this, we write the scale factor as a ratio first: 19/38, since 19 is the size of the model's length and 38 is the real length. For the second ratio, we have 18 for the size of the model wingspan and x for the real wingspan:
19/38 = 18/x
Cross multiply:
19*x = 38*18
19x = 684
Answer: x=3
Step-by-step explanation:
Move all x terms to the same side- x/2-x/3-1/2
Multiply to get common denominator- 3x/6-2x/6=1/2
Subtract 3x/6 and 2x/6 - x/6=1/2
Simplify - x=3
