Question

Find the breadth of a rectangle whose length is 12 cm and perimeter is 36 cm​

Answer 1

Answer:

Breath = 6 cm

Step-by-step explanation:

Let breadth = b

lenght = 12

perimeter formula = 2(l+b)

2 (12 + b) = 36

24 + 2b = 36

2b = 12

b = 6

Answer 2

Answer:

Breadth= 6cm

Step-by-step explanation:

Perimeter = 2(l+b)

2(12+b) = 36 cm

12+ b = 36/2

12 + b= 18

b= 18-12

b= 6
