Question

The perimeter of 110 cm and its length is 35 cm. what is the breadth of the rectangle?​

Answer 1

Given that: Perimeter of a rectangle is 110 cm. Length of that rectangle is 35 cm.

Need to find: Breadth of that rectangle

Concept: Formula of finding the perimeter is

☀ 2( l + b )

where,

• l is length
• b is breadth

_______________

Solution:

~By putting the values in the formula.

➡ 2( l + b ) = 110 cm

➡ l + b = 110/2

➡ l + b = 55 cm

➡ 35 + b = 55 cm

➡ b = 55 - 35

➡ b = 20 cm

• Henceforth, the breadth of that rectangle is of 20 cm.

Answer 2

Given,

The perimeter of rectangle  $110cm$ and its length is $35cm$.

Let breadth of a rectangle be $x$

Formula,

Perimeter of a rectangle $=2(l+b)$

Substitute given values, we get

$110=2(35+x)$

$55=35+x\\x=55-35\\x=20$

Therefore, the breadth of a rectangle is $20cm$.
