Question

find the area of quadrilateral PQRS whose vertices are P (-5,-3),Q(-4,-6),R(2,-3)and S(1,2)
​

Answer 1

Answer:

divide the quadrilateral in two triangle if the quadrilateral is square,rhombus or rectangle then the area of of the triangle will be equal.

Step-by-step explanation:

using area of triangle formula

area=1/2|[X1(Y2-Y3)+X2(Y3-Y1)+X3(Y1-Y2)|

put the values of terms for two triangles you will get the area and then sum up the area you will get the area of quadrilateral
