Question

What Is the formula of finding breadth of Rectangle?

Answer 1

Find the formula of the breadth of the Rectangle.

Consider $l$ as the length and $b$ as the breadth of the rectangle.

perimeter of rectangle is $P=2(l+b)$, where $P$ denotes the perimeter.

Equation of perimeter can be rephrase as follow:

$\begin{array}{rcl}P& =& 2\left(l+b\right)\\ & \Rightarrow & \frac{P}{2}=l+b\\ & & \Rightarrow b=\frac{P}{2}-l\end{array}$

Hence, the formula of the breadth of Rectangle is $\begin{array}{rcl}b& =& \frac{P}{2}-l\end{array}$ where $P$ denotes the perimeter
