The scale for the blueprints for a house is 1 in. = 7 ft. The dimensions ofa room on the blueprints are 2.5 in. By 3 in. What is the area of theactual room heeeeeeelp

Answer 1

Answer:

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!
