The lengths of the sides of a rectangle are 18cm by 3m. Express the area of the rectangle in square decametres.
lubasha [3.4K]

For this case we have that by definition, the area of a rectangle is given by:

A = b * h

Where:

b: It is the base of the rectangle

h: It is the height of the rectangle

By definition we have to:

1 meter equals 0.1 decameters

1 centimeter equals 0.001 decameters

According to the data of the statement we have:

b = 18 \ cm * \frac {0.001} {1} * \frac {decametres.} {cm} = 0.018 \ decameters.\\h = 3m * \frac {0.1} {1} * \frac {decameters} {m} = 0.3 \ decameters.

Thus, the area of the rectangle is:

A = 0.018 * 0.3 = 0.0054 \ decameters ^ 2

Answer:

0.0054 \ decameters ^ 2

If x is an even integer represent the next 3 even integer.
Ratling [72]
If x is even, say it's 2. Then what do you need to get to the next even integer (4)? You need to +2. So it would be x + 2, x + 4 and x + 6.
Or, it could be x multiplied. I.e. 2x = 4, 3x = 6, and so on so forth.
