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
1.08 is gonna be the answer
Since it's a square it must have 4 sides.
20÷4=5
area=l×w or b×h
5×5=25 (the sides of a square have the same length)
the area of the photograph is 25in²

Answer:
32 : 12 is the second equivalent ratio. = 48 : 18 is the third equivalent ratio. Therefore, the three equivalent ratios of 8 : 3 are 16 : 6, 32 : 12 and 48 : 18
Answer:
area= 452.39
circumference= 75.40
Step-by-step explanation:
circumference is equal to 2 * pi * r
area is equal to pi * r^2
circumference = 2 * pi * 12 = 75.40
area = pi * 12^2 = 452.39
