Question

find area of quardilateral pqrs​

Answer 1

AREA OF QUADRILATERAL PQRS =

AREA OF TRIANGLE PRS + AREA OF TRIANGLE PQR

=1/2 × 12 × 4 + 1/2 × 12 × 8 ( BECAUSE AREA OF TRIANGLE IS 1/2×BASE×HEIGHT)

=24+48

=72 sq. cm

Answer 2

Answer:

144 cm²

Step-by-step explanation:

Area of Quadrilateral PQRS = Length of diagonal * Sum of perpendiculars joining the other points to the diagonal = 12 * (4 +8)

   = 144 cm²

*Above answer is wrong, there is another formula for irregular quadrilaterals.Please mark as brainliest
