Question

If perimeter of rectangle is 128 cm and length is 15 cm.Find the breadth ?

Answer 1

Solution:-

Given:

• Perimeter = 128 cm
• Length = 15 cm

To Find:

• Breadth of rectangle

Step-by-step explanation:

❍ Let the breadth of rectangle be x cm respectively.

As we know that,

• Perimeter of rectangle = 2(l + b)

Applying the values,

➸ 128 = 2(15 + x)

➸ 128 = 30 + 2x

➸ 128 - 30 = 2x

➸ 98 = 2x

➸ x = 98/2

➸ x = 49

• ∴ Hence,The breadth of rectangle is 49 cm.

Answer 2

Answer:

$\huge\mathfrak\red{Question}$

• If perimeter of rectangle is 128 cm and length is 15 cm.Find the breadth ?

$\huge\mathfrak\red{answer}$

• perimeter of rectangle is 128cm
• length of rectangle is 15 CM
• so , multiply length by 2 => 15×2 = 30
• now subtract the result from perimeter
• 128-30 => 98
• now we have total length for remaining two side
• now divide 98 by 2 for find breadth
• 49 ans

$\huge\mathfrak\pink{formula}$

To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides. This number divided by 2 is the width
