Question

Lisa wants to frame her little brothers drawing as a gift to her mother.the rectangle drawing is 43.5 centimeters by 934 millimeters.How many centimeters of wood framing will she need

Answer 1

Lisa will need
`273.8\ cm` of wood framing

Explanation:

we know that

The perimeter of rectangle is equal to

`P=2(b+h)`

In this problem we have

`b=43.5\ cm`

`h=934\ mm`

convert to cm

Remember that
`1\ cm=10\ mm`

`h=934\ mm=934/10=93.4\ cm`

substitute the values and solve the perimeter

`P=2(43.5+93.4)=273.8\ cm`
