In the following figures, find the area of the shaded portions:


(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
