How does the area of the triangle relate to the area of the square? Please Explain!!! I really don't get it!

Answers

Answer 1

Answer: A square has 4 right angles and 4 equal sides.
If you draw a diagonal through the square then you get two right triangles. So the area relation between a square and a right triangle is going to be half. The area of the triangle is half the area of the square.

Also the formula for area of a square is length times width.
And the formula for the area of a right triangle is 0.5 times length times width.

So if you set up the equation (let's use * as multiplication symbol ):

Area of a Square : Area of a Right Triangle
length * width : 0.5 * length * width
(Divide by length * width on both sides)
1:0.5 or 2:1

Is 0.23 a rational number ?

Answers

The given number 0.23 which is the form of decimal is a rational number. The statement is true.

The number in the form of $(p)/(q)$ , where p is numerator and q is denominator and the denominator is not equals to zero, is called as rational number.

The given number 0.23 is a rational number which can be written as $(23)/(100)$ in the fraction form, where 23 is the numerator and 100 is the denominator, which is not equal to zero. So, the number can be considered as a rational number.

Thus, 0.23 is a rational number.

Yes, $\boxed{0.23}$ is a rational number.

Further explanation:

Real numbers includes all the rational numbers (integers and fraction) and all the irrational numbers.

Rational number is any number which can be expressed in the form of $(p)/(q)$ where $p$ and $q$ are integers and $q$ is non-zero and $(p)/(q)$ should be in the simplest form.

And those real numbers which are not expressed in the form of rational number are called irrational numbers.

For example: $\pi$ , $√(2)$ , $√(5)$ .

Here, the number is $0.23$ and which is in the form of decimal.

Express the number $0.23$ in the form of fraction as follows:

$0.23=(23)/(100)$

This implies that $(23)/(100)$ is the fraction form of $0.23$ .

Therefore, the fraction $(23)/(100)$ is in the form of $(p)/(q)$ where, $p$ is $23$ and $q$ is $100$ .

Also, here $q$ which is $100$ is non-zero.

Thus, $0.23$ can be written in the form of rational number.

Hence, $0.23$ is a rational number.
