On the blueprint of a house, 40 millimeters represents 6 meters. The length of the living room is 50 millimeters on the blueprint. What is the actual
length of the living room?

To find the actual length of the living room, start by establishing the ratio from the blueprint. Since 40 millimeters represents 6 meters, we can set up a proportion. First, determine how many times 40 millimeters fits into 50 millimeters:

50 mm / 40 mm = 1.25.

Now, multiply 6 meters by 1.25 to find the real-life length:

6 m * 1.25 = 7.5 meters.

So, the actual length of the living room is 7.5 meters.

To visualize it, think of it as if the living room on the blueprint is expanding like a balloon filling with air! Every 40 mm on that plan is just a piece of the puzzle making up the real space in your home. So imagine entering a living room that’s a spacious 7.5 meters long—plenty of room for all your furniture and maybe even a game of indoor soccer!
