To know which figure is more longer, We need to find it's perimeter.

a. Perimeter of Semicircle= Pie × r + d

= 22/7 × 1.4 + 2.8

= 22 × 0.2 + 2.8

= 4.4 + 2.8

= 7.2cm.

perimeter of first figure = 7.2 + 4

= 11.2cm.

b.perimeter of semicircle = 7.2 cm ( see above).

c. Perimeter of semicircle excluding diameter= pie × R

= 22/7 × 1.4

= 22 × 0.2

= 4.4cm

Perimeter of rectangle excluding one side of length= l + 2b

= 2.8 + 2 × 1.5

= 2.8 + 2.25

= 5.05cm.

Total perimeter = 5.05 + 4.4

= 9. 45cm.

So, figure A is having a longer path.
