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

Answer:

Lisa will need $273.8\ cm$ of wood framing

Step-by-step 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

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