Sally is making a scale drawing of her apartment. • She drew a line measuring 1 1/2 inches to represent the 12-foot width of her living room. • The length of her living room is 18 feet.
How long a line should Sally draw to represent the length of her living room?
A. 2 inches B. 2 1/4 inches C. 2 1/2 inches D. 3 inches
The answer is B We know that 1 1/2 is 12 foot So we divide it by 2 so we know every 6 feet how long is it so we will get 0.75 for each 6 feet. Now we divide 18ft by 3. We will have three sixs Now multiple 0.75 by 3 = 2.25 which means the answer is B And I attached a photo down so that helps more.
