Question

Find the perimeter of a rectangle whose:
Length $=8m$ and​
breadth $=80cm$

Answer 1

Step: Finding the perimeter of a rectangle

We have:
Length of the rectangle $=8m$ and
Breadth of the rectangle $=80cm$
$\because 100cm=1m$
$\therefore 1cm=\frac{1}{100}m$
And,
$80cm=\frac{1}{100}\times 80=0.8m$

The perimeter of the rectangle is given by:
$=2(Length+Breadth)=2(8m+0.8m)=2\left(8.8\right)=17.6m$

Therefore, the perimeter of the given rectangle is $17.6m$.
