Answer:
1.5cm
Step-by-step explanation:
perimeter of rectangles=2(l+b)
15=2(l+b)
15/2=6+b
b=15/2-6
b=7.5-6
b=1.5cm

Verified answer
Given:-
Perimeter of the rectangle=15cm
Length of the rectangle=6cm
To find:-
Breadth of the rectangle.
Solution:-
Let the breadth of the rectangle be b
We know,that perimeter of a rectangle is -----
=>2(l+b)=15
=>2(6+b)=15
=>12+2b=15
=>2b=15-12
=>2b=3
=>b=3/2
=>b=1.5cm
Thus,breadth of the rectangle is 1.5cm.
