Can anyone tell me the solution to this problem, I cant wrap my head around it

Determine a region whose area is equal to limn!1Xni=1 6/n (2 +2i/n) sqaured

. Hint - Look atthat will give you this sum. Also use the area interpretation of the definite integral

example 3 in section 5.2. There you are given the function and get a sum that looks

like this. Here you are given the sum and need to figure out a function and bounds
