(i)Area of parallelogram PMNQ is 240 cm²

(ii)Area of ∆PMQ is  120²

Step-by-step explanation:

Case 1: Finding the area of parallelogram PMNQ

From figure attache below, we can say that

Both the parallelogram LMNO and PMNQ are on the same base MN and lie between the same parallel lines MN and LQ.

We know that if two parallelograms are on the same base and lie between the same parallel lines, then they have the same area.

Area (parallelogram PMNQ) = Area (parallelogram LMNO) …. (i)

Since the area of parallelogram LMNO = 240 cm² ….(given) …… (ii)

Thus, from (i) & (ii), we get

The area of the parallelogram PMNQ = 240 cm²

Case 2: Find the area of ∆PMQ

From the given figure, we can say that  

The ΔPMQ and the parallelogram PMNQ have the same base PQ and lie between the same parallel lines PM and NQ.

We know that if a triangle and a parallelogram are on the same base and lie between the same parallel lines, then the area of the triangle is equal to half the area of the parallelogram.

Area (∆ PMQ) is given by,

= ½ * Area (parallelogram PMNQ)  

= ½ * 240  

= 120 cm²

Thus, the area of ∆ PMQ is 120 cm².
