plz also show working.​

Answer 1

Answer:

Well, I will give you an example (please do not worry)

Step-by-step explanation:

  Let’s consider an example:

If length of a rectangle is 10 cm and its perimeter is 22 cm, then find its breadth.

Given length, l = 10 cm and perimeter = 22 cm

We know that perimeter of rectangle = 2 (l + b) units

22 = 2(10 + b)

⇒ 10 + b = 11

⇒ b = 1 cm

Hence breadth of the rectangle is 1 cm.

In general, perimeter of rectangle P = 2(l + b)

(P/2) = l + b

⇒ b = (P/2) – l

Using above formula also you can directly find the value of breadth.
