Question

what is the formula of breadth of a rectangle when perimeter is given​

Answer 1

Answer:

Step-by-step explanation:

Perimeter = P

Length = l

Breadth = b

P=2(l+b)=2l+2b

2b=P-2l

b=(P-2l)/2

Answer 2

Answer:

Perimeter÷2–L=B

Step-by-step explanation:

Perimeter=2(L+B)

PERIMETER÷2=L+B

PERIMETER÷2–L=B

OR

PERIMETER=2(L+B)

PERIMETER=2L+2B

PERIMETER–2L=2B

PERIMETER–2L÷2 =B
