Answer 2

here you would get the total area as

45X30

But there are roads in between so the width is 1m each

but they have also ggiven that they are parrell to the sides sot that their lengths are equal to 45m and 30 m respectively

so we get our answer as 45X30-(1X45)-(1X30)

But we know if they intersect their areas will repeat so it would be like + sign

where at the point of intersection we need to add 1mX1m so final answer is

45X30-(1X45)-(1X30)+1mX1m = 1350-45-30+1 =1276

(inform me if i am wrong thanks)
