Step-by-step explanation:

${\huge{\boxed{\sf{\pink{☞Answe࿐★}}}}}$

Given :-

Length of wall = 100 m

Width of wall = 40.75 m

Cost per meter = 23 Rs

2.5 meters are left for entrance

The perimeter of the rectangle = 2(Length + Width)

= 2(100+40.75)

= > 281.5 meters

Therefore, the cost =

23×281.5

=> 6474.5 Rs

> 23×2.5 = 57.5 Rs

Therefore, the final cost :- 6474.5 - 57.5 = 6417 Rs
