These days we are seeing both 2 º ESO 3 º ESO as the equation systems at different levels of course. So guys, here are an exercise for the resolváis by a system of equations and not by "the account of the old" ...

For 2 º ESO The perimeter of a rectangle is 56 cm and 192 cm 2 area. Estimated its dimensions. (Hint: Draw a picture, called x eya sides and the easiest way is to apply the substitution method)

For 3 º ESO The diagonal of a rectangle is 20 cm and 192 cm 2 area. Estimated its dimensions. (Hint: Draw a picture, called x and y sides and the easiest way is to apply the substitution method, leading to an equation with algebraic denominators and then to a biquadratic)

are solutions same for both problems, it is the same shape and same dimensions.
