Problema Solution
To trim the edges of a rectangular table cloth, 48 feet of lace are needed. The length of the table cloth is exactly one-half its width. What are the demensions of the table cloth.
Answer provided by our tutors
the trim will go around the edges of the cloth, therefore the perimeter is 48 feet
p = 48
let the width = x
then the length = 1/2x
add up all of the sides and set them equal to 48
x + x + 1/2x + 1/2x = 48
3x = 48
x = 16
1/2x = 8
Therefore, the width is 16ft and the length is 8ft
