let the length =l=5x m
breadth =b =3x m
perimeter =128 m
2(l+b)=128
l+b =128/2
l+b =64
5x+3x=64
8x=64
x=64/8
x=8
therefore
length= l=5x=5*8=40 m
breadth =b =3x=3*8=24 m
area of the rectangle = l*b
=40 m * 24 m
=960 square meters
breadth =b =3x m
perimeter =128 m
2(l+b)=128
l+b =128/2
l+b =64
5x+3x=64
8x=64
x=64/8
x=8
therefore
length= l=5x=5*8=40 m
breadth =b =3x=3*8=24 m
area of the rectangle = l*b
=40 m * 24 m
=960 square meters
