Question

find the area of quadrilateral formed by A(0,4) B(3,2) C(3-2)and (-2,-2).​

Answer 1

Answer:

Step-by-step explanation:

Area of Quadrilateral is equal to Area of triangle ABC + Area of triangle ACD

(I am using ║ for modulus)

Area of ΔABC = 1/2║0[2+2] + 3[-2-4] + 3[4-2]║

= 6

Area of ΔACD = 1/2║0[-2+2] + 3[-2-4] - 2[4+2]║

= 15

Area of quadrilateral = 15 + 6 = 21
