Answer:
These are both 20 so that means that this is proportional, yes.
Step-by-step explanation:
Hi.
To figure this out we can do something called cross multiplying to find a cross product. If we do this and our two answers are equal then it is indeed a proportion.
Here is how we do this.
So basically what we are doing is multiplying across in a diagonal direction.
Diagonal meaning like a slash / .
So in this case we would multiply the 4 and the 5 , since they're diagonal from each other.
Do the same for the 2 and the 10.
So we have to multiply :
4 x 5
2 x 10
=
20
These are both 20 so that means that this is proportional, yes.
Hope this helps.

Answer:
132 ft²
Step-by-step explanation:
First we shall work out the area of 1 skylight. one skylight is 15/8 feet so 15/8 x 15/8 = 3.515625 feet. x this by 2 as there is 2 skylights. So in total, there is 7.03125 feet^2 covered by the skylights. Take this from the original area 140ft - 7.03125 ft = 132.96875 ft^2 or as a mixed number 132 ft²
The height is 240 How this helps
