Question

the length and width24

Answer 1

put options and check them thats one simple method or

l=x
so, b=74-x

therefore area = x*(74-x) = 74x - x^2
now, same as any equation, maximise th eequation

so diffrentiate it and equate it to zero for optimum x

A' =74-2x = 0

so, x=37.

so the other side is also 37. l=b=37.

so its a square!!
