Q1 is true because if two things are parallel may they be lines or planes, they can never intersect since the will always be parallel. As for Q2, you have to find the area of the smaller rectangle and the larger one. You then subtract the area of the smaller one from the larger one to find it's area. 4 times 1 is 4 so 4 is the smaller rectangles area. 7 times 13 is 91 so 91 is the larger rectangles area. 91 - 4 is 87. This means the area of the shaded part is 87 meters squared
