Answer :
Set up a proportion:
3.9/11.7 = 13.2/x
Cross multiply:
3.9x = 154.44
Divide 3.9 to both sides:
x = 39.6
So the shadow for an object that is 13.2 will be 39.6 feet long.
3.9/11.7 = 13.2/x
Cross multiply:
3.9x = 154.44
Divide 3.9 to both sides:
x = 39.6
So the shadow for an object that is 13.2 will be 39.6 feet long.
