Tablecloth lace reserve

Mom wants to sew a tablecloth for a table measuring 75 × 110 cm so that it hangs 20 cm over the edge on each side. She also adds a 20 cm reserve for hemming. How much lace does she need to buy to trim the edge?

Final Answer:

x =  550 cm

Step-by-step explanation:

a=75 cm b=110 cm  p=2 dm cm=2 10  cm=20 cm  A=a+2 p=75+2 20=115 cm B=b+2 p=110+2 20=150 cm  x=p+2 (A+B)=20+2 (115+150)=550 cm
