Question

if A(-5,7) B(-4,-5) C (-1 ,-6) andD (4,5) are the vertices of a quadrilateral, find the area of the quadrilateral ABCD

Answer 1

first draw this in a graph. They have already said that it is a quadrilateral, so check whether its right.
Then count the box inside the quadrilateral formed.
area= length * breadth 
therefore, take the length and the breadth of the quadrilateral and multiply it.
The answer what u get is the area of that quadrilateral.

I hope it helped..!
