Why does the area of 70 times 30 equal 2100 but the area of 50 times 50 equal 2500 square feet?

If you have two pairs of numbers whose sum is the same, their product increases as the two numbers get nearer to half the sum. The product is a maximum at that value.
70 * 30 = (50+20)*(50-20)
The right hand side is the factorisation of the difference of two squares, and can be shown to be equal to
502 - 202
Since 202 must be positive (it is a square), 70*30 must be less.
For all values of x, (50+x)*(50-x) is less than or equal to 50*50=2500
with equality attained only when x = 0.
