Answered by kvnmurty

size of rectangle: a X b.

So 100 = 2(a²+b²) => a² +b² = 50

In a rectangle the length of the diagonal
= √(a² + b²) = √50 = 5√2

===============================
The other problem:

$\frac{2^{1001}-2^{1000}}{2^{501}-2^{500}}\\\\\frac{2^{1000+1}-2^{1000}}{2^{500+1}-2^{500}}\\\\=\frac{2^{1000}*(2 - 1)}{2^{500}*(2-1}\\\\=2^{1000-500}=2^{500}$

mukesh3: how did u do the third line

mukesh3: i cant understand

mukesh3: in the second question

mysticd: take common 2 power 500 in two terms

mysticd: which line from the above

mukesh3: mystic now i understood
