Answer:
Let x be the breadth of rectangle.
Therefore,
Length of rectangle (l)=(x+3)
Perimeter of rectangle =38m
As we know that,
Perimeter of rectangle =2(l+b)
∴2((x+3)+x)=38
⇒2x+3=38
2
⇒2x=19−3
⇒x= 16=8m
2
Therefore,
l=x+3=8+3=11m
Hence the length and breadth of rectangle is 11m and 8m respectively.
