Question

what is formula of find breath

Answer 1

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.  

Answer 2

if area is given
then area of rectangle= l×b
so, b= a/l
