Answer 1

Answer:

The answer of this question is 45 cm

Answer 2

Answer :

[ Option ( a ) 45 cm ] is the correct option.

Step-by-step explanation :

To Find,

• The breadth

Solution,

Given that,

• Perimeter of the rectangle = 230 cm
• Lenght = 70 cm

Therefore,

As we know that,

Perimeter = 2 ( Length + Breadth )

A . T . Q

» 2 ( 70 + Breadth ) = 230

» 70 + Breadth = 230 / 2

» 70 + Breadth = 115

» Breadth = 115 - 70

» Breadth = 45

∴ Hence, Breadth of the rectangle is 45 cm.

Now, Verification

As we know that,

Perimeter = 2 ( Length + Breadth )

By putting the values,

» 230 = 2 ( 70 + 45 )

» 230 = 2 × 115

» 230 = 230

L.H.S = R.H.S

Hence, Verified !
