"The length of a rectangle is twice the width. the area is 50 yd^2" -----> LW=50
and L=2W

--->
(2W)W=50

2W^2=50
W^2=25

W=5...

L=2*5=10

Ans: width: 5, length: 10

.................................

" A student opens a mathematics book to two facing pages" ----> x(x+1)=2162

x^2+x=2162

x^2+x-2162=0

(x-46)(x+47)=0

x=46, x=-47

Ans: pages are 46 and 47
