Re: 10 second questions

Hi,

Certainly, zetafunc!

In haste, I missed a part of the question. By oversight, and also due to receding light. The correct question ought to have been

What is the approximate value of 69!?

In other words, how many digits would 69! contain.

Hi zetafunc,

#6279. If in a rectangle, the length is increased and breadth reduced each by 2 units, the area is reduced by 28 square units. If, however the length is reduced by 1 unit and the breadth icreasedby 2 units, the area increases by 33 square units. Find the area of the rectangle.
