Answer:
66 ft
Step-by-step explanation:
It is given that the windows on a building are proportional to size of the building.
Height of each window = 18 in
Width of each window = 11 in
Height of the building = 108 ft
Let the width of the building be x.
Since windows on a building are proportional to size of the building, therefore
On cross multiplication we get
Divide both sides by 18.
Answer:
66 ft
Step-by-step explanation:
What your doing is setting up a proportion that of the windows(18x11) dimensions and the buildings(108xW) dimensions.
So it would be 18/11=108/x
you would cross multiply so you would have 11x108 (1188)= 18x
Divide by 18 so x=66
