konstantin123 [22]

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
