Question

6. Find the area of composite figures:​

Answer 1

Answer:

a) Area of rectangle+Area of right triangle = Area of the whole figure

Area of rectangle=l×b

Area of right triangle =1/2×base × height

Further,

11×7

77m

1/2×7×6

21m

Therefore total area is

21+77=98m

b)area of triangle + area of semi circle=area of the figure

1/2×12×9=54m

1/2×22/7×6×6

396/7m

57+396/7

57+56.56

113.56m
