What is area of rectangle?

The area of any shape is the number of unit squares that can fit into it. Here "unit" refers to one (1) and a unit square is a square with a side of 1 unit. So, the area of a rectangle is the number of unit squares within the boundary of the rectangle.

Here, Scale : 1 inch = 3 ft.

Let, the length of the bedroom on blue print be x inches and breadth be y inches.

then the actual length of bedroom will be 3x ft. and actual breadth will be 3y ft.

Area in blue print = xy = 12 sq. inches

Area of actual bedroom = length X breadth

                                        = 3x X 3y

                                        = 9xy

                                        = 9 X 12

                                        = 108 sq. ft.

Thus, the actual square footage size of the bedroom will be 108 sq. ft.
