Question

find the area of quadrilateral abcd whose vertices are a(-3 -1) b(-2 -4) c(4 -1) and d(3 4)

Answer 1

First u have to find the distance between all the points i.e ab,bc,cd,da. Then u will get the length of the sides and use the area formula of the quadrilateral.
The fromula of distance is .....


√(x2-x1)*(x2-x1)+(y2-y1)*(y2-y1)
