South Dakota.----Many have a rough shape of a rectangle, but Wyoming and Colorado seem to be nearest to a true rectangle.

As far as I can see I would say exactly zero.

The area of the WHOLE rectangle is less than 0.01 sq metres. So it is a lot less than a cent (which is 40 metres2 ). So to the nearest tenth of a cent, the area of the circle, which will be smaller than that of the rectangle, is 0. No calculations required.

Use Pythagoras' theorem: 1272+76.22 = 21935.44 and the square root of this is 148.1061781 Answer: 148 to the nearest cm

I can and will. So if you put the diagonal through a rectangle you create a right angled triangle of which you can use pythagoras theorem. x2 = 152 + 62 x2= 261 x = 16.16m

It could be any value in the range (2.65, 2.75) square units.

Suppose you had a rectangle that was 12.75 units by 19.6 units. The area would be 249.9 square units which would round to 250 square units to the nearest square unit. Since a centimeter isn't a square unit, it can't be rounded to the nearest square unit.

Use the Law of Pythagoras - in this case, the answer is the square root of (162 + 92).

Draw a diagonal line across the rectangle. The resulting two right triangles will each have identical areas half that of the rectangle. The area of the rectangle is its height x base, and the area of each of the two triangles is 1/2 of its height x base.

The flag is divided horizontally into a red (top) and blue (bottom) rectangle. From the side nearest the flagpole - extends a white equilateral triangle containing a gold 1 large, and 3 small stars.
