Answers
Answer:
(a) 14 m^2
(b) 10 m^2
(c) 28 m^2
(d) 39 m^2
Step-by-step explanation:-
(a) Name the figure as shown above
Join FI and EJ
In rectangle AFIB,
AF = 2 m
AB = 3 m
Therefore, area of rectangle AFIB = (3 × 2) m^2
= 6 m^2
In rectangle GHJI,
GH = 1 m
GI = (3 - 1) m
= 2 m
Therefore, area of rectangle GHJI = (1 × 2) m^2
= 2 m^2
In rectangle EDJC,
area of rectangle EDJC = area of rectangle AFIB
= 6 m^2
Therefore, area of the complete figure
= (6 + 6 + 2) m^2
= 14 m^2
(b) Name the figure as shown above
Join CI and DJ
Area of the complete figure
= Area of rectangle (ABCI + HIJG + EFJD)
= (1 × 3 + 1 × 3 + 4 × 1) m^2
= (3 + 3 + 4) m^2
= 10 m^2
(c) Name the figure as shown above
Join EF
Area of the complete figure
= Area of rectangle (ABCD + EFGH)
= (10 × 2 + 4 × 2) m^2
= (20 + 8) m^2
= 28 m^2
(d) Name the figure as shown above
Join DI
AB = GH + IC
= (3 + 5) m
= 8 m
DG = AG - AD
= 5 m
Area of the complete figure
= Area of the rectangle (ABCD + DIHG)
= (8 × 3 + 3 × 5) m^2
= (24 + 15) m^2
= 39 m^2
