Properties of Rectangle:
Opposite sides are parallel and equal
Each angle in rectangle is 90
But in Trapezoid only one pair is parallel and angles are not 90.
So A trapezoid is not a rectangle
Properties of square.
Opposite sides are parallel. all sides are equal and each angle is 90.
So, square can be a rectangle.
It is given that AE and DF are parallel lines. Line GH intersect both lines. Line AE intersects with line GH at point B, line DF intersects with line GH at point C. As shown in the below figure.
m∠ABG = 11x and m∠HCF = 10x + 9.
From the below figure it is clear that ∠ABG and ∠HCF are alternate exterior angles. So, measure of these angles are equal.
The value of x is 9.
Therefore, the correct option is B.

100page in 4 days
1 day=54/3=18 pages
160 pages =5 days
1 day=160/5=32 pages
average page=[25+18+32]/3=25 pages per day is a required rate.
