Question

(6) Find the breadth of the rectangle having
Length = 8 cm and Perimeter =18 cm​

Answer 1

Answer:

1 cm

Step-by-step explanation:

l=8cm

Perimeter=18 cm

Perimeter=2(l+b)

18=2(8+b)

18=16+2b

2b=18-16

2b=2

b=1cm

Answer 2

Step-by-step explanation:

2(l+b)=perimeter

let breadth be x,length=8cm

2(8+x)=18

8+x=18÷2

8+x=9

x=1

breadth =1cm
