Question

find the perimeter of a rectangle whose lenth is 28 cm and breath is 20 cm ???​

Answer 1

Answer:

Step-by-step explanation:

2[l + b]

2 x [28+20]

= 2 x 48

= 96

Answer 2

Answer:

Therefore the value of the perimeter of a rectangle (P) is 96 cm.

Step-by-step explanation:

As per the data provided in the given question.

The given data is as follows,

The length of a rectangle(l)is 28 cm and the breadth of a rectangle(b)is 20 cm.

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

The breadth of a rectangle(b) represents the width of the rectangle i.e.(w).

Here we will be using the formula of the perimeter of a rectangle.

$P=2(l+w)$

Now we will substitute the value of l and w in the above formula.

Further, we get

$=2(28+20)$

At first, we will add the term inside the bracket

We get,

$=2(48)\\=2\times48$

Now we will multiply 2 into 8 get 16 and 2 into 4 get 8

We get,

$=96\;cm$

Therefore the value of the perimeter of a rectangle (P) is 96 cm.
