Step-by-step explanation:
As pentagon has 5 sides,
Perimeter of pentagon=5s.....where s is the side of a pentagon
=5x10=50cm.................(1)
Perimeter of a rectangle=2(l+b)
=2(17+12)
2x29=58cm...................(2)
Therefore, the perimeter of the rectangle is more than that of the perimeter of pentagon........(from1 and 2)
The difference between the perimeter of two polygons is 58-50=8cm
