Answer 2

Answer:

mixed fraction-45   3/7cm

Step-by-step explanation:

given

diameter of the semicircle=6cm

radius of the semicircle=6/2=3cm

width of the rectangle=12cm

length of the rectangle=6cm

perimeter of a whole circle=2*pie(or 22/7)*radius

2*22/7*3=132/7cm

perimeter of a semi circle= {perimeter of a whole circle}/2

132/7*1/2=66/7

primeter of the rectangle=2(l+b)

2(12+6)

2*18

36cm

perimeter of the whole fig =66/7+36

252/7+66/7                                             (lcm)

318/7cm

mixed fraction-45   3/7cm
