Question

The perimeter of a rectangle is 60cm, and the length is 18cm. Find it's Breadth.(Answer should come 12cm)

Answer 1

Answer:

12 cm

Step-by-step explanation:

Let Breadth be x then

We know perimeter of rectangle = 2(l + b)

=> 2(x + 18) = 60

=> x + 18 = 30

=> x = 12 cm

Hence breadth = 12 cm

Answer 2

Answer:

12 cm

Step-by-step explanation:

Perimeter of rectangle = 2(l+b)=60 cm

2(18+b)= 60

18+b=60/2

18+b=30

b=30-18

b=12cm
