perimeter of rectangle is=2(L+b)
56=2(3+x)
56÷2=3x
28=3x
28-3=x
25=x
56=2(3+x)
56÷2=3x
28=3x
28-3=x
25=x

let the width of rectangle be x
then, length = 3x
Perimeter of rectangle = 2(l+b)
56m = 2(3x+ x )
3x+ x = 56m/2
4×= 28m
x = 28/4m
x = 7m
now, length = 3x
3x = 3×7m
3x= 21m
Hence, length = 21m
then, length = 3x
Perimeter of rectangle = 2(l+b)
56m = 2(3x+ x )
3x+ x = 56m/2
4×= 28m
x = 28/4m
x = 7m
now, length = 3x
3x = 3×7m
3x= 21m
Hence, length = 21m
