We have given that MNOP is a parallelogram.
since parallelogram MNO and triangle PRM are on the same base PM and between same parallels PM and ON
∴ ar (ΔPRM) =1/2 ar(║MNOP) ......(1)
similarly ║MNOP and triangle PQO are on the same base PO and between same parallels PO and MN
∴ ar (ΔPQO ) = 1/2ar(║MNOP)........(2)
from equation 1st and 2nd
ar (ΔPQO) =ar(Δ PRM)
ar(ΔPQO) = 12 cm² (∵ ar(ΔPRM) = 12 cm ²)
