Another Babylonian problem is
To the area of a rectangle, the excess of the
length over the width is added, giving 120%3;
moreover, the sum of the length and width is
24. Find the dimensions of the rectangle.
[Hint: The problem can be put in the form of two
equations xy +x - y = 120, x + y = 24; if the
substitution y = z – 2 is made, the system becomes
x +z = 26, xz = 144.]
