"hello everyone i am sumanjali math tutor from leader learning welcome to question and answer session given question is write the coordinates of the vertices of a rectangle whose length and breadth are 5 and 3 units respectively one vertex at the origin the longer side lies on the x-axis and one of the vertices lie in the third quadrant okay so there are many questions was give many clues was given in the question so first of all length and breadth okay so length is given as a five units five units and breadth is given as three units okay this was the first clue so we need to prepare a rectangle who's a longer side whose longer side is five and shorter side is is three okay so this is a five and this is three okay so the second one is one vertex at the origin so origin is here okay so at this particular point one vertex will lie i'm just keeping that particular vertex so this is vertex whose coordinates are zero comma zero okay so second the next clue is the longer side lies on the x-axis if this is if this is the origin so it should be like yeah so there is a chance of the longer side is lies on x-axis that means longer side maybe lies here or lies here also okay so this is also x axis this is also x axis okay so one of the vertices lie in the third quadrant okay so this is the first quadrant we know that this is the first quadrant this is the second quadrant this is the third quadrant and this is the fourth quadrant as they already said one of the vertex lie in this particular region only okay so there is a chance of plotting plotting rectangle here only because this is one vertex this is one vertex okay so probably the two vertices should be in this region only okay so now i'm plotting that okay so the length and breadth are five and three okay so and also we know that the longer side will lies on x axis okay so preferably this is a longer side in which this direction only we should keep our longer side and in this direction only we should keep our smaller side okay yeah so we know that length is five units and breadth is three units okay so i'm just plotting that from point o okay so if we plot five if we plot five units so it is the length okay it is the length this is the length and this will become breadth okay so this is one two and three this will becomes a breadth okay yeah so this is an another one and this is an another one okay so let let us keep the names of the vertices as this is point o this is a this is b and this is point c okay so our rectangle whose four vertices are so first of all o zero comma zero and a x coordinate is minus five and y coordinate is zero and b whose x coordinate is x coordinate is minus 5 and minus 5 and y coordinate is minus 3 and the last one is c whose x coordinate is 0 and y coordinate is y coordinate is minus 3 okay so now we already forms forms a rectangle this is a rectangle abcd okay hope you understand if you have further questions reach us at comment section and subscribe to the channel leader learning for further queries thank you"
