Area of parallelogram EBFD = EB x BC
Area of parallelogram AEFC =AE x AD
BC=AD = y

Adding both of the area
EB * y + AE * y =3+2
(EB + AE) *y =5 = AB *y
So area of reactangle ABCD =5
Option :C

Area of Parallelogram - base * height


hence if area of EBFD is 3, that means that base is 3 and height is 1 ---> 3*1=3

simiralry area of AECF is AECF, meaning base is 2 and height is 1 ---- > 2*1 =2

Area of rectangale base is 2+3 =5 and height is 1, so 5*1 = 5

so answer is C i think :)
