width --- x
length ---- x+3
2x + 2(x+3) = 30
solve for x

If 10 less theeen a number is -10 then the number is
Let the breadth(width)=x
Let the length=x+3
We know that
Perimeter of rectangle=2(length+width)
30m=2((x+3)x)
30m\2=2x+3
15m-3=2x
x=12/2=6m
Length=6+3m=9m
Let the length=x+3
We know that
Perimeter of rectangle=2(length+width)
30m=2((x+3)x)
30m\2=2x+3
15m-3=2x
x=12/2=6m
Length=6+3m=9m
