Answer:
- Area of Shaded region = 105 Sq. units
Soln.:-
Area of the given rectangle = l(b) sq. unit
= 12(20)
= 240 Sq. unit
Area of ∆DEG = 1/2(12)(5)
= 30 sq. unit
Area of ∆CFB = 1/2(14)12
= 84 sq. unit
Area of ∆EAF = 1/2(6)7
= 21 sq. unit
Now,
Area of shaded region = Area of rectangle - { Area of -> ∆DEG + ∆CFB + ∆EAF }
= 240 - { 30 + 84 + 21 }
= 240 - 135
= 105 Sq. units
