Question

Q. The perimeter of rectangle is 15 cm. If the length of the rectangle is 6 cm, then its breadth will be.​

Answer 1

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

Answer 2

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.
