what is the diagonal math measure to squaring a square, rectangle?

Question

my four sides are equal in length but it's crooked ! lenght x width? i can't figure it out! please help! and i wish to make also a small rectangular footing !

Answer 1

it is the breadth of the rectangle

Answer 2

Use the pythagorean theorem. A squared + B squared = C squared. A and B are the length sides of the square or rectangle and C is the lengh of the diagonal. For example, in a perfect square, the diagonal of the square should measure the length of one of the sides multiplied by the square root of 2.

Answer 3

once you employ a diagonal in both a sq. or a rectangle, you're making 2 acceptable triangles of equivalent length and section. hence, in case you recognize the lengths of both sides, you should use the pythagorean theorum to confirm what the hypotonuse-the diagonal-is. So it can be one area squared plus the different area squared, then the sq. root of that.

Answer 4

Use the old rule that builders have used for years,

The 3 - 4 - 5 rule that works on a right angled triangle.

Measure 3 units along one side and mark that point, 4 units along the other side and mark that point, measure between the two marked points and it should be 5 units, if it isn't then you need to move one side until you acquire the 5 unit measure.
(unit = mm, cm, M whichever you are working in

Answer 5

if i have understood your question correctly the answer is in a square and a rectangle the diagonals will be equal.if they are not the rectangle becomes a parallelogram and the square becomes a rhombus

Answer 6

If you're talking about a 'parallelogram' it's the base times the height. Look in any book on elementary geometry.
