Question

Answer 1

first we have to find the perimeter of the rectangle

21×14=214

now find the perimeterof a circle

2×22/7 ×14/7

=2×22×14

=2×308

=616

as it is a semi_circle we should divide it by 2

=616÷2

=308

perimeterof the shaded region =perimeter of ( semi circle _rectangle)

= 308_214

94 cm
