Question

a rectangle has a perimeter of 26 CM if its length is 9 cm what is this breadth​

Answer 1

Step-by-step explanation:

Given= perimeter of rectangle=26 cm,

length= 9 cm,

we know that,

perimeter of rectangle=2(l+b),

so,

26=2(9+b)

26÷2=9+b

13=9+b

13-9=b

so b=4 cm

Answer 2

Answer:

Length=9cm,and perimeter=26

Then

Perimeter of rectangle=2(l+b)

26=2(9+b)

26/2=9+b

13=9+b

b=13-9

b=4
