Question

6. Perimeter of a rectangle is 155 m. If the length is 45 m, find its breadth.​

Answer 1

Answer:

breath=32.5

Step-by-step explanation:

perimeter=2(l+b)

155=2(45+b)

155/2=45+b

77.5=45+b

77.5-45=b

breath=32.5

Answer 2

✬ The breadth of rectangle is 32.5 m ✬

Step-by-step explanation:

As we know that,

• Perimeter of rectangle = 2(l + b)

Where,

• Perimeter = 155 m
• Length = 45 m
• Breadth = b m

Putting the values,

➣ 155 = 2(45 + b)

➣ 155 = 90 + 2b

➣ 155 - 90 = 2b

➣ 65 = 2b

➣ b = 65/2

➣ b = 32.5 m
