Question

what is the formula of finding the breadth by using perimeter and length​

Answer 1

Answer:

Formula to calculate the perimeter of rectangle is as,

2(l+b)

so, to calculate the breadth it is as,

Perimeter-2l/2=b

I hope it helps.......

Answer 2

Answer:

2b = P - 2L

»» b = P - 2L/2

Step-by-step explanation:

Simply,

As we know Perimeter of rectangle is 2(L+B).

So,

we can make its formula easily,

even we don't have to make formula. The answer will come easily if we have already given the breadth and perimeter.

______________________

For better understanding, let's take an example.

Suppose in the question you have the length as 4 and perimeter as 12 and you have to find the length.

So, we'll just write it as it is actually -

2(L+B) = P

2(4+B) = 12

8 + 2B = 12

2B = 12-8

2b = 4

»» b = 2.

Or else, use the formula -

2b = P - 2L
