if you have ten foot square what is the measurement corner to corner?

We can do this 2 different ways.\n\nFirst: Use the Pythagorean Theorem. Since all angles are right angles, the diagonal (measure from corner to corner) is the hypotenuse of the right triangle formed.\n\nBy the Pythagorean Theorem, 10^2 + 10^2 =x^2, where x=diagonal\n\nx^2=200\nx=sqrt(200)\nx=10 sqrt 2\n\n2nd way: use 45-45-90 Triangles\n\nWhen you draw any diagonal in a square, you get a 45-45-90 degree right triangle. This is because the 2 sides are the same, so the 2 base angles must be also. The top is 90, so the others must be 45 and 45 to equal each other.\n\nThe sides to a 45-45-90 right triangle are always in the ratio 1:1: sqrt(2) where sqrt(2) is the hypotenuse.\n\nYou know that the sides are 10 feet. Therefore the hypotenuse is 10 sqrt2 feet

you need 20 cans of varnish. 60x80 =4800 sq feet.. since one can does 250.00 you have another 4550 sqfeet still to do..20 cans needed  or 19.2 cans

Actually it depends on the layout of the meters.  If it is a true square, it would be 2x2 meters... so 2 meters wide.  It is also possible to have four square meters be 4x1 meters.\n\nMore information is needed.

The long way to do this is much simpler:\n\n1) convert everything into inches and re-write the problem.\n2) do the easy math\n3) see how many times 12 goes into your new answer (that'll be the number of feet in your answer)\n4) then add on the remainder (that'll be the number of feet in your answer)

You have to find an area.  If ou have one foot by one foot, it is one square foot.  If the area is circular, find the area of the circle.

4x10 , 8x5 it amounts to 4ft x10ft

Area = pi*r^2 = pi*3^2 = 9pi. Thats 28.27 square feet, approx.

You need to measure the outside walls, not the square footage. Vinyl siding is measured in running feet, not square feet. Measure the length of each of your outside walls, than measure the height of the walls, and include the gabels if your putting siding there, this is very important, especially if you have a split level home. Take these measurements with you to the Home Depot, Sears wherever your buying the siding.

Google calculator will give you the answer right away.\n\nJust type "sq ft in an acre" and you'll get back the answer of 43,560 sq. ft.\n\nOr if you want it in sq inches, type "sq inches in an acre" (6,272,640 sq inches).

ANSWER : 25 square units.\n\n---------------------------------\n\nFirst off, draw a picture. \nSo, you have one point on the (0,0), one on the x-axis, one on the y-axis, and one on the diagonal line.\n\nLet's call the length of the horizontal line segment of the rectangle w.\n\nThe other side will then be (10-w).\n\nSo, the area of the rectangle is A = w*(10-w).\n\nIf you graph this, there is a maximum at the point (5,25), so 25 is the max area.\n\nTo verify this, take the derivative of A with respect to w, and set equal to zero.\nA' = 10 - 2w = 0\n2w = 10\nw = 5\nA = 5(5) = 25

It's difficult to know your options without knowing how big the building is and what shape it is. If the walls are at right angles then the length of the curved corner will be a quarter or the circumference from which you can find the radius. The radius would be twice the length divided by pi.\nIf not then, aside from taking a mould and working with tangents, I can't think of an easy way.\nThe answer above will work very well if you have access to the face of the curve.

I assume the shape to be rectangle.\n\nMeasure the longer side in feets and name it L\nand the shorter side as B\n\nThen multiply L*B you get measure in square feets.\n\nIf it is irregular in shape, you have to cut it into parts and draw lines and measure each area separately.
