A = ( 40 - 2 * 2 ) * ( 25 - 2 * 2 ) = ( ( 40 - 4 ) * ( 25 - 4 ) = 36 * 21 = 756 m ^ 2

Remark:
Length and width have path 2 meter wide for both sides.
That's why we need to reduce their sizes by 2 m * 2 m
Area of rectangle :
A = a * b
where
a = L - 2 * 2 = 40 - 2 * 2 = 40 - 4 = 36 m
b = W - 2 * 2 = 25 - 2 * 2 = 25 -4 = 21 m
So :
A = a * b = 36 * 21 = 756 m ^ 2
