Question

If $P$ denoted perimeter of a rectangle, $l$ denotes its length and $b$ denotes its breadth find;
$b$, if $P=3.2cm$ and $l=100cm$

Answer 1

Given
$P=3.2m$ and $l=100cm=1m$
The breadth of the rectangle $\left(b\right)$ can be calculated as follows
Here, the length is in centimetre. Hence, it ca be converted into metre from centimetre as below
Length $=100cm$
$=100/100m$
Breadth $\left(b\right)=P/2-l$
$=3.2/2-1m$
$=1.6m-1m$
We get,
$=0.6m$
Hence, the breadth $\left(b\right)$ of the rectangle $=0.6m$
