chenri356 100 sq is 100^2=100*100=10000 meter,but 100 meter square is a area unit such as your house is length 10 meter and wide 10 meter, so 10*10=100 meter square. Hope to help you.

chenri356 It's very easy. a1=1+1*0,a2=2=a1+1*1,a3=a1+1*2,……an=a1+1*(n-1)=n n=? a1+a2+a3+……an=100 =a1+a1+1+a1+2+a1+3+……a1+n-1 =n*a1+0+1+2+3+……+n-1 =n*1+(0+n-1)*n/2 (a1=1) =100 so n+n^2/2-n/2=n^2/2+n/2=100 turning chien gets n^2+n=200 (n^2+n-200=0) result:...
