== == IMPORTANT : Some people have been creating multiple accounts to enter the Lenny Conundrum multiple times, to win multiple prizes or to improve the chances of winning. Please do not do this, it makes the game unfair for others. We will freeze the accounts of people that we find doing it. Also, giving out the answer or obvious hints is against the rules. Please help to make the Lenny Conundrum fair for everyone! == == Imagine starting by putting the diameter of the Pizza directly in the corner of a box but at a 45 degree angle. That makes a 45-45-90 triangle with the hypotenuse being 50 cm.

Now take the midpoint of this and draw your semicircle. The distance from this point up will be the radius (25 cm). And down will be the side of a triangle with hypotenuse 25. This ends up being 25/√2.

So one dimension would be 25 + 25/√2, and so would the other. Multiplying this together we get:

(25 + 25/√2)²

= 25² + 50*25/√2 + (25/√2)²

= 625 + 1250/√2 + 625/2

≈ 625 + 883.883 + 312.5

≈ 1821.383 sq. cm

Since they want us to round to the nearest whole number, the answer is 1821 sq. cm
