Question

A rectangle has an area of 45m2

and a width of 3m. In meters,
what is the sum of the length
and the width of the rectangle?

Answer 1

Sum of the length and width =
`18\,m`

Explanation:

Area of the rectangle=
`45\,m^2`

`Width=3\,m`

Area of the rectangle=
`Length* Width`

`45=Length* 3\\\\Length=(45)/(3) \\\\Length=15\,m`

The sum of the length and width of the rectangle is:

`=15+3\\\\=18\,m`
