The perimeter of a rectangle = 164 m

2(l + b) = 164

l + b = 82 --- (1)

l - b = 22 ---(2)

By solving the equation (1) and (2), we get,

l = 52, b = 30

Area of rectangle = lb = 52 * 30 = 1560

Area of Square = 1560 - 39 = 1521

Side (a) = 39 m

Outer Side of the path = 39 + 2 * 2.5 = 44 m

So, area of the path = 44² - 39² = (44 - 39)(44 + 39) = 415 m²

Hence, total cost of paving the path = 415 * 8 = Rs. 3320
