Answer: (SCROLL DOWN FOR FIGURE)
Dimensions of outer rectangle = 40 m by 30 m
Dimensions of inner rectangle =
[40 m-(1.5 m*2)] by [30 m-(1.5 m*2)]
=(40 m-3 m) by (30 m-3 m) = 37 m by 27 m
Area of outer rectangle = l*b = 40 m*30 m =
1200 m^2 (A1)
Area of inner rectangle = l*b=37 m*27 m =
999 m^2( A2)
Area of pathway
= A1-A2
=1200 m^2 - 999 m^2
=201 m^2
