Let the overlapping region (DXY) be x cm2.
ABXDYC = ABC - x
EXYF = DEF - x
So, the difference between ABXDYC and EXYF
= (ABC - x) - (DEF - x)
= ABC - x - DEF + x
= ABC - DEF
= (12 * 8 / 2) - (6 * 4 / 2)
= 48 - 12
= 36 cm2
The answer is 36 cm2.
ABXDYC = ABC - x
EXYF = DEF - x
So, the difference between ABXDYC and EXYF
= (ABC - x) - (DEF - x)
= ABC - x - DEF + x

= 48 - 12
= 36 cm2
The answer is 36 cm2.
