a=3
b=2
c=diagonal
a squared add b squared equals c squared
9 add 4 = 13
square root 13 and ther's your answer
Length = (1/2 of perimeter) minus (Width) Diagonal = square root of [ (Length)2 + (Width)2 ]
18.9 feet
3.606 inches (rounded)
Anything you want, so long as (Length in inches)2 + (Width in inches)2 = 1,764
The diagonal can be found by taking length^2+width^2=diagonal^2 13^2=x^2+(x+7)^2 169 = x2 + x2 + 14x + 49 120 = 2x2 + 14x x2 + 7x - 60 = 0 now just factor, and you have the answer. It's the positive x value.
Length = (1/2 of perimeter) minus (Width) Diagonal = square root of [ (Length)2 + (Width)2 ]
The diagonal is 3.61cm
18.9 feet
To find the length of the diagonal of a rectangle, you can use the Pythagorean theorem. In this case, the diagonal forms the hypotenuse of a right triangle with the sides being the length and width of the rectangle. So, the diagonal (d) can be calculated as d = √(4^2 + 6^2) = √(16 + 36) = √52 ≈ 7.21 feet.
3.606 inches (rounded)
62 +82 = 102 so 6 and 8
Anything you want, so long as (Length in inches)2 + (Width in inches)2 = 1,764
Suppose the width is W and the diagonal is D.Then, by Pythagoras's theorem, the length, L, is given by L = sqrt(D^2 - W^2).And then, area = L*W.
Length = 4, Width = 2
The perimeter of a rectangle is found by the following formula: (Length x 2) + (Width x 2) or Length + Length + Width + Width.
You would usually measure the length and width of the rectangle, then calculate other magnitudes based on that. However, it's possible that you already know some other data about the rectangle. Here are some formulae that relate the different dimensions of a rectangle: area = length x width perimeter = 2 x (length + width) diagonal = square root of (length^2 + width^2) In any case, you need to know SOME of these measurements, to be able to calculate the others.
You can't. Suppose for instance your rectangle is 1xA, then the diagonal length is sqrt(1+A**2). But if your rectangle is sqrt(A)xsqrt(A) then your diagonal length is sqrt(2*A). The only thing one can say for sure is that the diagonal length is at least sqrt(2*A).
