Question
In a Trapezium ABCD, as shown, 
and 
then length of AB is
- 40 cm
- 50 cm
- 80 cm
- 60 cm
Hint:
A convex quadrilateral having exactly one set of opposite sides that are parallel to one another is called a trapezium. When drawn on a piece of paper, the trapezium is a two-dimensional shape that resembles a table. Here we have given a Trapezium ABCD where and , we have to fond the length of AB.
The correct answer is: 40 cm
Now we know that a quadrilateral with one set of parallel opposite sides is a trapezium. The bases and legs of a trapezium are referred to as parallel and non-parallel, respectively. It also goes by the name trapezoid. The parallelogram is occasionally referred to as a trapezoid with parallel sides.
Here we have given trapezium ABCD as:
Here we used the concept of trapezium and parallel lines. A closed polygon or geometry with four sides, four corners, and four angles is called a trapezium. Each pair of a trapezium's opposing sides is parallel to the other. Here the length of AB is 40 cm.

The point which divides the line segment joint the points A(7,-6) and B(3,4) in the ratio 1:2 internally lies in the
Here we used the concept of line segment and section formula, the coordinates of the point that splits a line segment (either internally or externally) into a certain ratio are found using the Section formula. Here the x coordinate is positive and y coordinate is negative, so it lies in IV quadrant.

2 women and 5 men can together finish an embroidery work in 4 days while 3 women and 6 men can finish it in 3 days What is the time taken by 1 woman alone?
So here we used the substitution method to solve the question, apart from this method we can also use the elimination method to solve the problem as we have variables here. So the total number of days taken by a woman is 18.
