OpenStudy (anonymous):

do you need to find the area of the qudrilateral formed using the above vertices..

OpenStudy (anonymous):

yes ofc

OpenStudy (anonymous):

I was doing it incorrectly

OpenStudy (anonymous):

sry sry sry sry

OpenStudy (anonymous):

I used incorrect formula

OpenStudy (anonymous):

first plotting the points on a graph paper wil help, and then find the area of the triangle formed with the vertices (0,0) ,(6,0) and (0,3) and then agin find the are of the triangle formed by ,(6,0) , (0,3) and (4,3) add the area of the two triangles to get the area of the qudrilateral

OpenStudy (anonymous):

the triangle formed (0,0) ,(6,0) and (0,3) with vertices is a rt angled one so area here is 1/2 * 6*3 = 9 sq. units... and so on..

OpenStudy (anonymous):

15 i am geting , @matricked

OpenStudy (anonymous):

This is formula based

OpenStudy (anonymous):
