Question

A rectangular sheet of metal is 40 inches wide and 100 inches long. What is its perimeter?

Answer 1

Explanation

We are given the following:

`Rectangle\begin{cases}width={\text{ }40inches} \\ length={\text{ }100inches}\end{cases}`

We are required to determine the perimeter of the rectangular sheet.

This is achieved thus:

We know that the perimeter of a rectangle is given as:

`P=2(l+w)`

Therefore, we have:

`\begin{gathered} P=2(100+40) \\ P=2(140) \\ P=280inches \end{gathered}`

Hence, the answer is:

`280inches`
