Class 10 Area
Class 10 Area
Answer:-
As per the Diagram
EC = BC (Radius in Sector BGEC)
Hence EC = 7 Cm.
DE = 4 cm Given
DC = DC + EC
= 4 CM + 7 CM = 11 cm
Area of trapezium ABCD
= (1/2) *( Sum Of ||el sides) * (Height)
= (1/2) * (AB+DC) *(BF)
=(1/2) * (7 cm + 11 cm ) * (3.5 cm )
= 0.5 * 18 cm * 3.5 cm
= 9 cm * 3.5 cm
= 31.50 cm2
Area of Sector BGEC :-
(O/360) *( pi *r*r)
= (30/360) *(22/7*7*7)
(1/12) * (22*7)
= 12.83 cm2
Area Of shaded portion = Area of trapezium - Area of Sector
= 31.50 cm2 - 12.83 cm2
= 18.67 cm2
Hence the Right answer is (d).
