 Hi and welcome to the session. I am Neha and today I am going to help you with the following question. The question says the shape of the top surface of a table is a trapezium. Find its area if its parallel sides are 1 meter and 1.2 meter and perpendicular distance between them is 0.8 meter. Here is the figure of the table. Now before proceeding for the solution let's recall the formula of area of trapezium. Area of trapezium is 1 by 2 into sum of parallel sides into this is the key idea for this question. Now let's see its solution. Here in this question we are given that the parallel sides are 1 meter and 1.2 meters. So for the trapezium or let's say for the top of the table length of parallel sides is equal to 1 meter and 1.2 meter. Also the height of the top of the table that is trapezium is 0.8 meter. As in question we are given that the perpendicular distance between the parallel lines is 0.8 meters. Therefore area of the top of the table is equal to half into sum of parallel sides and parallel sides are 1 meter and 1.2 meter. So 1 meter plus 1.2 meter into height and height is 0.8 meter. So this is equal to 1 by 2 into 1 plus 1.2 into 0.8 meter square. That is 1 by 2 into 2.2 into 0.8 meter square which on simplifying gives 0.88 meter square. Therefore area of the top of the table is 0.88 meter square and this is a required answer. So with this we finish this session hope you must have understood the question. Goodbye take care and have a nice day.
