Ответ:
367.5 square feet
Step-by-step explanation:
So, we know that for 1 inch on a bluesheet its 7 feet in a room.
We know area is L*W.
We know one length is 2.5in, and the other is 3in
lets convert this using the 1in:7ft ration above:
2.5*7ft
=
17.5ft
3*7ft
=
21ft
So we know the room is 21ft by 17.5ft
Now lets plug these two values in for the area formula above(L*W):
21ft*17.5ft:
367.5ft^2
Or
367.5 square feet.
Hope this helps!
