Question 1158794

1. How many yards of lace trim should be purchased to make borders for two rectangular tablecloths each with width {{{4}}} feet and length {{{6}}} feet?

lace trim should be the length equal to the sum of perimeter of both tables
since tables are same dimensions, double the perimeter of one table
{{{2(2*4+2*6)=2(8+12)=2*20=40}}}

 
convert ft to yd 
{{{1ft=0.33333yd
{{{40ft=40*0.33333yd=13.333yd}}}

=> to make borders, should be purchased {{{13.333}}} yd  of lace trim


2. How many centimeters of edging are needed for a rectangular table measuring {{{2.5}}} meters by{{{5}}} meters?

table measuring {{{2.5}}} meters by{{{ 5 }}}meters have a perimeter of



 {{{2(2.5+5)m=2*7.5m=15m}}} 

{{{1m=100cm}}}=> {{{15m=1500cm}}}

so, {{{1500}}} centimeters of edging are needed for a rectangular table measuring {{{2.5 }}}meters by {{{5 }}}meters
