Question

plz anyone give answer I will mark as brainlist


Find the area of the shaded regions for the following figure

Answer 1

( b ) area of rectangle = l×b
20×12 =240

area of triangle = 2(1/2 × b× h)
2(1/2 x12×10)=120
now subtracting area of rectangle from triangle=area of shaded region.
240-120=120cm.sq.

(c) area of square= side× side
4×4=16
area of circle= 3(/\.r sq.)
3(3.14×1) = 9.42
Now subtracting area of circle from square
16 - 9.42=6.58

Answer 2

1)area of rectangle =l×b
=20×12
=240cm2
Area of 4triangle =1/2×10×6×4
** =30×4
=120cm2
Area of shaded region =240-120
120cm2
2)area of square =4×4
=16cm2
Area of 3 circle =22/7×1×1×3
=66/7
=9.4cm2
Area of shaded region =16-9.4
=6.6cm2
