Question

Length and breadth of a rectangle are 12.3cm and 9.6cm respectively. Find its perimeter

Answer 1

Answer:

43.8cm

Step-by-step explanation:

Perimeter of rectangle = 2(l+b)

l=12.3cm

b=9.6cm

just put it in the formula

2(12.3+9.6)cm

2(21.9)

43.8cm

Answer 2

Given,

Length of a rectangle = 12.3 cm

The breadth of a rectangle = 9.6 cm

To find,

The perimeter of the rectangle.

Solution,

The perimeter of the rectangle will be 43.8 cm.

We can easily solve this problem by following the given steps.

We know that the perimeter is the sum of all the sides of the given shape. In a rectangle, the opposite sides are of the same length and all the angles are of 90°.

So,

The perimeter of the rectangle (P) = 2(length+breadth)

P = 2(12.3+9.6)

P = 2(21.9)

P = 43.8 cm

( More to know: The area of the rectangle is length×breadth.)

Hence, the perimeter of the rectangle is 43.8 cm.
