Lisa's drawing has the following dimensions:
Width=43.5 cm
Length=934 mm
but 1 cm =10 mm
thus
934mm when converted into cm we shall have:
length=93.4 cm
To get the total length of material required to frame the picture, we calculate the perimeter.
P=2(L+W)
P=2(93.4+43.5) cm
P=2(136.9)
P=273.8 cm
The total length of material required will be 273.8 cm
the answer you are looking for is 5 9/20 pounds
sorry but it as to be twenty character
let length of one piece = x
length of other piece = 236-x
one piece is three times the length of the other
x=3(236-x)
x=708-3x
4x=708
x=177
so first piece is 177 inches long and second piece is (236-177)= 59 inches long
