(i) We have to find out the Area of (EFDC):

Area of EFDC = Area of ABCD – Area of BCE – Area of AFE

= 180 – 40 – 30

= 180 – 70

= 110 cm²

(ii) We have to find out the Area of QTU:

Area of QTU = Area of PQRS – Area of TSU – Area of RUQ – Area of PQT

= 400 – 50 – 100 – 100

= 400 – 250

= 150 cm²
