Area of green shaded region=
Area of rectangle - ( Area of triangle DEF + Are of triangle BEC)
Area of rectangle = L × B
= 18 × 10
= 180 cm2
Area of triangle DEF= 1/2 × base × height
= 1/2 × 10×6
= 30 cm2
Area of triangle BEC = 1/2 × base × height
= 1/2× 8×10
= 40 cm2
Area of green shaded region=
Area of rectangle - ( Area of triangle DEF + Are of triangle BEC)
= 180 cm2-(30 cm2+40 cm2)
= 180 - 70
= 110 cm2
