A scale drawing of a living room is shown below. The scale is 1 : 40. A rectangle is shown. The length of the rectangle is labeled 6 inches. The width of the rectangle is labeled 4 inches. Show your work to determine the area of the room in square feet.

The scale ratio of a point A to another point B is the division of the length of B by the length of A. The area of the room is approximately 266.67 square feet.

Given that:

--- length of rectangle

--- width of rectangle

Divide by 12 to convert the dimensions to feet

means that the dimension of the room is 40 times the dimension of the rectangle.

So, we have:

The area of the room is:

So, we have:

The area of the room is 266.67 square feet
