How do you find area of square if diagonal is given?
Using Pythagoras' theorem which says that the square on the hypotenuse (in this case the diagonal) is equal to the sum of the squares on the other two sides (which in the case of a square would be equal in length). so if the diagonal measured 10 units, the square on the diagonal would be 100 square units. And as this = 2*the squares on the other sides, the square on one side would be 100/2 = 50 square units. As a square has sides of equal length the square on one side is actually the area of the square. i.e. the area of a square with a diagonal of 10 units is 50 square units. or generically the area of a square with a diagonal of length 'x' = (x2)/2

How is an iPad measured?
If you mean the screen size, then it is measured by the diagonal of the screen from corner to corner.
Is the size measured on a diagonal for flat screen television sets?
Yes, the size is generally measured in inches from corner to corner. A 26" television, therefore, is 26" across the diagonal, and therefore slightly shorter in the horizontal and vertical directions.
Diagonal measurement of a rectangal?
The diagonal of a rectangle is measured by using Pythagores theorem if you have the length and breadth of the rectangle. Say the length is 4cm and breadth is 3cm then the diagonal(hypotenuse) would be 42 + 32 =16 + 9= 25 = 52. Hence the hypotenuse or the diagonal is 5cm. Is that fine? Have a good day.
How many 18x18 tiles to cover diagonal 211 sq ft?
A diagonal would be measured in feet, not square feet. Given the length of a diagonal, it is not possible to determine the shape of the area to be covered. Without information about the shape, its area cannot be calculated.
What does an upward sloping diagonal line mean in position vs time graph?
It means that either the distance is measured from the starting-line and the object is moving forward, or else the distance is measured from the finish-line and the object is moving backwards, because the distance is growing as time goes on. If the upward sloping diagonal line is straight, it means the speed is constant. (not velocity)
How do you measure the size of a computer screen what does it mean if the screen size is 14?
screen size of any computer or tv screen is measured along the diagonal. so screen size 14 inches means that the length of the diagonal of the screen is 14 inches
Why is my 40 inch TV not measure 40"?
yes, you have most probably measured this television wrong. you are meant to measure the television from corner to corner IE diagonal. you have most probably measured it along the length of the TV set.
How are TVs measured?
The display size of the screen is measured on the diagonal. For instance, lower left hand corner to upper right hand corner. For the TV itself, the size will vary on the case design.

Name 3 things measured in centimeters?
A person's height (eg for passports), TV screen size (it is usually the diagonal rather than the surface size which would be in square cm), Bed linen.
Give three examples of monitor screen sizeshow are monitor screen sizes measured?
Monitors are currently transitioning from CRT to LCD as a standard. Sizes include 15", 17", 19", and larger, in either the standard or widescreen format. These inch measurements are diagonal, from bottom left to upper right of the viewable area.
