Question

find the breadth of the rectangle if perimeter is 124 centimeters and length is 28 cm​

Answer 1

☆ Solution ☆

Given :-

• The perimeter of the rectangle is 124 cm.

• The length of the rectangle is 28 cm.

To Find :-

• The breadth of the perimeter.

Step-by-step-Explaination :-

Let,

• The breadth of the rectangle be b.

Now,

As we know that :-

Perimeter of the rectangle = 2 ( length + breadth )

Where,

• The perimeter of the rectangle = 124 cm.
• The length of the rectangle = 28 cm
• The breadth of the rectangle = b

Putting the respective value,

124 = 2 ( 28 + b )

124 = 56 + 2b

2b = 124 - 56

2b = 68

b = 68/2

b = 34

Hence,

The breadth of the rectangle is 34 cm.

Answer 2

We know that,

$\rm{\dag{\boxed{\red{Perimeter_{(Rectangle)} = 2(l + b)}}}}$

⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━━

⠀

$\sf{\underline{According\: to\: the\: question}}$

⠀

$\sf{\dashrightarrow{124 = 2(28 + b)}}$

⠀

$\sf{\dashrightarrow{124 = 56 + 2b}}$

⠀

$\sf{\dashrightarrow{2b = 124 - 56}}$

⠀

$\sf{\dashrightarrow{2b = 68}}$

⠀

$\sf{\dashrightarrow{b = \dfrac{68}{2}}}$

⠀

$\mathfrak{\dashrightarrow{\boxed{\pink{b = 34}}}}$

⠀

Hence,

• The breadth of the rectangle is 34 cm.
