Answer:
none of the above
Step-by-step explanation:
Area of the shaded portion
= area of the rectangle - area of the semi circle
AREA OF RECTANGLE
= l×b sq. units
=8×10 =80cm²
AREA OF SEMI CIRCLE = πr²
2
note: radius =4
=22x4² = 176/7
7×2
=25.14 cm²
there are 2 semicircles of same measures
hence 2×25.14
50.28 cm²
area of shaded portion =80-50.28
=29.72 cm²
