First convert the height of the man to feet:
6 feet 3 inches = 6.25 feet ( 3 inches is 1/4 of a foot)
Now set up a ratio:
Light House would be height over shadow = 119/45
Man would be height over shadow, which we will call X for now, so 6.25/X
Set the ratios to equal:
119/45 = 6.25/x
To solve for X cross multiply:
119X = 45*6.25
119x = 281.25
Divide both sides by 119 to find x:
X = 281.25 / 119
X = 2.36
The mans shadow is 2.36 feet long.
The answer is A.
