Question

Perimeter of a rectangle is 50cm and its length is 15cm what is its breadth

Answer 1

The breadth of the rectangle = 10 cm

Given :

Perimeter of a rectangle is 50 cm and its length is 15 cm

To find :

The breadth of the rectangle

Formula :

Perimeter of a rectangle = 2 × (Length + Breadth)

Solution :

Step 1 of 2 :

Write down perimeter and length of the rectangle

Here by the given condition ,

Perimeter of the rectangle = 50 cm

Length of the rectangle = 15 cm

Step 2 of 2 :

Find breadth of the rectangle

Let breadth of the rectangle = b cm

We know that ,

Perimeter of a rectangle = 2 × (Length + Breadth)

Thus we get

2 × (15 + b) = 50

⇒ 15 + b = 50/2

⇒ 15 + b = 25

⇒ b = 25 - 15

⇒ b = 10

Hence breadth of the rectangle = 10 cm

Answer 2

Answer:

Breadth of rectangle = 10cm

Step-by-step explanation:

Given:

Perimeter = 50 cm

Length = 15 cm

Breadth =?

Perimeter of rectangle = 2 (l + b)

50 = 2 ( 15 + b)

50/2 = 15 + b

25 = 15 + b

25 - 15 = b

10 = b

or, b = 10 cm

Breadth of rectangle = 10 cm

Rectangle:

• Perimeter is the measure of the length of all the edges of a closed figure.
• Rectangle: A rectangle is a two-dimensional shape (2D shape) in which the opposite sides are parallel and equal to each other and all four angles are right angles.
• Perimeter of a rectangle: Rectangle has four sides, and the opposite sides are equal and parallel.
• Thus, Perimeter = l + l + b + b = 2 (l + b)
• Area = l X b
