Let the length be 2x-6 and the width be x:

(2x-6)*x = 140 square meters

Mutiply out the brackets:

2x2-6x = 140

2x2-6x-140 = 0

Solving the above equation using the quadratic equation formula will result in:

x = -7 or x = 10 so it must be the latter because dimensions can't be negative.

Therefore: length = 14 meters and width = 10 meters

Check: 14*10 = 140 square meters

Rooms are generally rectangular in shape, so the floor space is the length times the width. Add up all the rooms (and corridors or other spaces) and you get the total for the house. If you have spaces that are not rectangular, then the calculations become a bit more complicated, but you can usually estimate a rectangular equivalent.

The answer depends on the shape of the room. If it is rectangular, then it is the product of its length and width - both measured in feet. For any variation - for example, bay windows, alcoves, L-shaped rooms, the determination is less simple.

Then the height is at LEAST 9 meters (3 floors each 3 meters high) You would need to add any height of the foundation and roof- if any.

Discrete. You cannot have 3.76... rooms!

Rooms are usually measured in feet. The width times the length gives you square feet. Dividing by 9 gives you square yards. 9 square feet is 1 square yard.

The size of the Inca's house, known as a "kancha," can vary depending on the social status of the individual or family. In general, Inca houses were rectangular and relatively small, typically measuring around 5-7 meters in width and 10-15 meters in length. They were made of stone, adobe, and thatch, and often had one or two rooms.

it is less expensive to build.

Some rooms have more, some have less.Here's how to calculate the volume of your own room:-- Measure the length of the room in meters.-- Measure the width of the room in meters.-- Measure the height of the room in meters.-- Calculate the product of all three numbers.-- Multiply the product by 1,000.-- The last number is the room's volume in liters.

You would use the metric unit "meters" to measure the length of a room.

Because it's easier to make rectangular measurements that circular ones, and also, it would be pretty hard to make circular furniture, too! Rectangles are just easier to work with.
