A rectangular park is 45m long and 30m wide .A path 2.5m wide is constructed out side the park find the area of path

long without path  =45 m
wide without path =30 m
area without path  =  long x wide
area = 45 x 30
        =1350 m²
long with path =45+2.5+2.5=50m
wide with path = 30+2.5+2.5= 35m
area with path = 1750m²
area of path = 1750-1350
                = 400 m
