Answer 2

Answer :

The length of the rectangle is 3cm.

Step-by-step explanation :

To Find,

• The length of the rectangle

Solution,

Given that,

• The perimeter of rectangle = 22 cm
• Breadth of rectangle = 8 cm

Therefore,

As we know that,

Perimeter = 2 ( l + b )

Where,

• l = Length
• b = Breadth
• h = Height

By putting the values,

➯ 22 = 2 ( Lenght + 8 )

➯ Lenght = 22/2 - 8

➯ Length = 11 - 8

➯ Length = 3

∴ Hence, the length of the rectangle is 3cm.

Now, Verification

As we know that,

Perimeter = 2 ( Length + Breadth )

By putting the values,

➯ 22 = 2 ( 3 + 8 )

➯ 22 = 2 × 11

➯ 22 = 22

L.H.S = R.H.S

Hence, Verified !
