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%282%2A4%2B2%2A6%29=2%288%2B12%29=2%2A20=40

convert ft to yd
1ft=0.33333yd%0D%0A%7B%7B%7B40ft=40%2A0.33333yd=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 by5 meters?
table measuring 2.5 meters by+5+meters have a perimeter of


2%282.5%2B5%29m=2%2A7.5m=15m
1m=100cm=> 15m=1500cm
so, 1500 centimeters of edging are needed for a rectangular table measuring 2.5+meters by 5+meters
