Let the length of rectangle be x
Perimeter of rectangle =2 (length +breadth)
190=2 (x+35)
190=2x+70
2x=120
x=60m
area of rectangle =length × breadth
=35×60
=2100 m^2

perimeter=2(l+b)
=>2(l+b)=190m
=>l+35=190÷2
=>l+35=95
=>l=95-35
=>l=60m
therefore, a=l*b
a=60*35
a=2100m^2
=>2(l+b)=190m
=>l+35=190÷2
=>l+35=95
=>l=95-35
=>l=60m
therefore, a=l*b
a=60*35
a=2100m^2
