Question

the perimeter of a rectangle is a 230 cm,if the length of the rectangle is 70 cm,find its breath ​

Answer 1

Answer:

Breadth = 45 cm

Step-by-step explanation:

Given,

Perimeter = 230 cm

Length = 70 cm.

Breadth = b.

We know, Perimeter = 2 ( l + b )

230 = 2 (70+b)

230/2=70+b

115=70+b

115-70=b

b=45cm

Answer 2

Given:

• The perimeter of the rectangle is 230 cm.
• The length of the rectangle is 70 cm.

Need to find:

• The breadth of the rectangle = ?

Solution:

Let the breadth of the rectangle be "x".

As we know that,

⋆ Perimeter = 2 × (length + breadth)

Putting the values:

➜ 2 × (70 + x) = 230

➜ (70 + x) = 230/2

➜ (70 + x) = 115

➜ x = 115 - 70

➜ x = 45

Therefore,

The breadth of the rectangle is 45 cm.
