Answer:
length = 14cm width = 7cm
Step-by-step explanation:
length = 2x w (width)
if length = 2x width then
length must equal 4/6 and width must equal 2/6 because length is 2 times width.
42 divded by 6 = 7.
length gets four lots of 7.
length of both sides= 28cm
width gets 2 lots of 7.
width of both sides= 14cm
there are two sides for length and two sides for width.
Length x 2= 28cm
Length must equal 14cm.
Width x 2 = 14cm
Width must equal 7cm.
lets just prove this is true:
7+7=14.
14+ (14+14) =
14+ 28= 42cm.
this works.
the length is 14cm and the width is 7cm.
