Each side will increase by the square root of 69 (approx. 8.3).
200%. Careful here! An 800% increase is equivalent to multiplying by 9 - NOT 8. So the sides need to be multiplied by sqrt(9) = 3. That is an increase of 200%
If the linear dimensions of a square or a rectangle are doubled, the area of the object will be quadrupled.
This needs more information. Without some other factor, like a change in area, the width doesn't have to increase at all.
It is a measure of how much something has increased by.
Before the increase, it's 20. After the increase, it's 36.
30%

The mitochondrial membrane's cristae are similar in size to villa lining the intestine and are there for much of the same purpose, to increase surface area for absorption.
If the linear dimensions of a square or a rectangle are doubled, the area of the object will be quadrupled.
This needs more information. Without some other factor, like a change in area, the width doesn't have to increase at all.

To double the area of a circle, you need to increase the radius by a factor equal to the square root of 2, or by about 1.414.Recall the formula for the area of a circle is 2 pi r2. Well, 2 pi is constant, so look at r2. In order to double the contribution of r2 you need to increase r by a factor equal to the square root of 2.
800 increased by 500 percent is: an increase of 4,000 for a total of 4,800.
If you are referring to the area of a rectangle, it will increase by 3 times the width. The area of a triangle will increase by 3 times 1/2 the base or, in other words, 1 1/2 times the base. (This answer presumes you mean the height increases by three units, such as inches or millimeters, not by three times the original height.)
