AI Thread Summary
To find the dimensions of a rectangular field with a perimeter of 60 meters and an area of 200 square meters, the equations for perimeter (p = 2a + 2b) and area (A = ab) are used. By substituting the perimeter equation into the area equation, one can express one variable in terms of the other. Solving these equations simultaneously will yield the lengths of the sides a and b. Drawing a diagram can aid in visualizing the problem. The solution will provide the specific dimensions of the field.

Please help me I beg you!
 
Show how you have tried to approach the problem.
 
I need somebody to show me how to do it.
 
Try not to be lazy.

The perimeter of a rectangle is p=2a+2b=60 meters, where a and b are contiguous sides' lengths. Do you see this? (Drawing a figure would be helpful.)

The area A=200 meters2. In terms of a and b the area is thus equal to...
 
Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...
Thread 'Imaginary Pythagoras'
I posted this in the Lame Math thread, but it's got me thinking. Is there any validity to this? Or is it really just a mathematical trick? Naively, I see that i2 + plus 12 does equal zero2. But does this have a meaning? I know one can treat the imaginary number line as just another axis like the reals, but does that mean this does represent a triangle in the complex plane with a hypotenuse of length zero? Ibix offered a rendering of the diagram using what I assume is matrix* notation...
Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...
