Tablecloth

The table top is 90 cm long and 50 cm wide. How many cm lace edging is necessary for the tablecloth that hangs on each side by 10 cm?

Correct answer:

x =  360 cm

Step-by-step explanation:

$$\begin{gathered} a=90\text{ cm } \\ b=50\text{ cm } \\ {a}_1=a+2\cdot 10=90+2\cdot 10=110\text{ cm } \\ {b}_1=b+2\cdot 10=50+2\cdot 10=70\text{ cm } \\ x=2\cdot (a_1+b_1)=2\cdot (110+70)=360\text{ cm} \end{gathered}$$
