Lisa wants to frame her little brothers drawing as a gift to her mother.the rectangle drawing is 43.5 centimeters by 934 millime
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

What is the length of the diagonal of a square with a side that measures 11 centimeters
timofeeve [1]
A square has 4 equal sides
use pythagroeas theorem since a square has 4 right angles

a^2+b^2=c^2
a=b because the sides are equal (11)

11^2+11^2=c^2
242=c^2
square root both sides
11√2=c

the diagonal legnth is 11√2 centimiters
