The total area of the park is (100*100) = 10,000m^2 

The road covers 90m on 2 of the sides of the park, and 100m on the other 2 sides, so: 

90*5 = 450 (5 because the width of the road is 5m) 
450*2 = 900 (2 because there are 2 sides in which the road covers 90m) 

100*5 = 500 
500*2 = 1,000 

So now we add them to find the total area the road covers: 

900+1000 = 1,900m^2

Side of park = 100 m
path constructed = 5  m
now the side = 100 + 5 = 105 m
now area of the park s= 4[s]2 = 4 [105 ]2=11025 x 4 = 44100
