Answer:
Area of the square is 2916
.
Step-by-step explanation:
Let the breadth of the rectangle be represented by w. So that;
length of rectangle = 5w
Area of rectangle = length x breadth
= 5w x w
1620 = 5![w^{2}](https://tex.z-dn.net/?f=w%5E%7B2%7D)
divide through by 5 to have,
= 324
w = ![\sqrt{324}](https://tex.z-dn.net/?f=%5Csqrt%7B324%7D)
= 18
Thus, the breadth of the rectangle is 18 m.
length = 5 w = 5 x 18
= 90 m
The length of the rectangle is 90 m.
Perimeter of the rectangle = 2(l + w)
= 2( 90 + 18)
= 216 m
Perimeter of a square = 4l
where l is the length of its side.
Given that the perimeters of the rectangle and square are equal, then;
4l = 216
l = ![\frac{216}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B216%7D%7B4%7D)
= 54
length of the side of square is 54 m.
Therefore,
Area of square = ![l^{2}](https://tex.z-dn.net/?f=l%5E%7B2%7D)
= ![54^{2}](https://tex.z-dn.net/?f=54%5E%7B2%7D)
= 2916
Area of the square whose perimeter is equal to that of the rectangle is 2916
.
The right answer for the question that is being asked and shown above is that: "B. X^2 = 5.85 p = 0.88." The answer that would be the appropriate type of test to investigate our hypothesis is that <span>"B. X^2 = 5.85 p = 0.88." This is the correct answer.</span>
Answer:
The number 10/7 is a rational number, which means it can be expressed as a fraction. Also, if we divide it would give a decimal infinite periodical number, which means it has a pattern on its decimal numbers.
On the other hand, the square root of 2 is irrational number, that means it can't be expressed as a fraction, because its decimal numbers don't have any pattern at all.
So, Mai's brother can see these type of numbers as crazy (irrational numbers) and sane (rational numbers).
At last, another important characteristic to shows that they aren't equal is that they don't have the exactly decimal numbers.
I think it is D the answer choose
