Question

find the perimeter if lenth = 12cm and breadth = 13cm

Answer 1

Answer:

PERIMETER: 312cm

Step-by-step explanation:

FOR RECTANGLE : 2(LENGHT+BREATH)

LENGTH: 12cm

BREATH: 13cm

PERIMETER : 2(12 X 13)

                    =2(156)

                    =312cm

Answer 2

Answer:

Hence the perimeter of a rectangle is $50\;cm^{2}.$

Step-by-step explanation:

As per the data provided in the question,

The given data is as follows.

The length of a rectangle (l) is 12cm,

the breadth of a rectangle (b) is 13 cm.

We need to find the value of the perimeter of a rectangle (P).

Breadth is represent the width of the rectangle (w).

We will use the formula of the perimeter of a rectangle.

$P=2(l+w)$

We will substitute the value in the above formula.

$P=2(12+13)$

At first, we will add the value inside the bracket.

$P=2(25)\\P=2\times25$

We will multiply 5 into 2 we get 10 and 2 into 2 we get 4.

$=50\;cm^{2}$

Hence the perimeter of a rectangle is $50\;cm^{2}.$

NOTE: find the perimeter of the rectangle if lenth = 12cm and

breadth = 13cm.
