On the scale drawing of a floor plan 2 inches= 5 ft. A room is 7 inches long on the scale drawing. Find the actual length of the room.
2 / 5 = 7 / x Multiply both sides by x
2 x / 5 = 7 Multiply both sides by 5
2 x = 7 * 5
2 x = 35 Divide both sides by 2
x = 35 / 2
x = 17.5 ft
Well, if 2 inches on the scale drawing represents 5 feet in reality, then we can use a bit of math and clown logic to solve this.
First, let's figure out how many feet are represented by one inch on the scale drawing. Since 2 inches represent 5 feet, that means 1 inch represents 5 divided by 2, which is 2.5 (keep up, it's simple!).
Now that we know that 1 inch represents 2.5 feet, we can multiply this by the length of the room on the scale drawing, which is 7 inches.
7 inches multiplied by 2.5 feet per inch equals... drumroll please... 17.5 feet!
So, the actual length of the room is 17.5 feet. And remember, when measuring in the real world, it's always better to use a tape measure than a clown's ruler!
To find the actual length of the room, you can set up a proportion using the scale of the drawing. The proportion can be set up as:
2 inches / 5 feet = 7 inches / x feet
To solve for x, you can cross-multiply:
2 inches * x feet = 7 inches * 5 feet
2x = 35
To isolate x, divide both sides of the equation by 2:
x = 35 / 2
x = 17.5
Therefore, the actual length of the room is 17.5 feet.
To find the actual length of the room, we can set up a proportion using the scale factor given in the problem.
The scale factor is 2 inches = 5 feet, which can be written as:
2 inches / 5 feet
We know that on the scale drawing, the room is 7 inches long. Let's call the actual length of the room "x feet".
So, we can set up the proportion:
2 inches / 5 feet = 7 inches / x feet
To solve for x, we can cross multiply:
2 inches * x feet = 7 inches * 5 feet
2x = 35
Now, divide both sides of the equation by 2:
x = 35 / 2
x = 17.5
Therefore, the actual length of the room is 17.5 feet.
