Tablecloth 72254

The table top is 1.2 m long, 55 cm wide, and 35 mm thick. Calculate how many regular meters of a 1 m wide roll are needed for a tablecloth that extends 15 cm beyond the bottom edge of the table on all sides.

Correct answer:

z =  1.57 bm

Step-by-step explanation:

$$\begin{gathered} a=1.2\text{m} \\ b=55\text{cm}\to \text{m}=55:100\text{m}=0.55\text{m} \\ h=35\text{mm}\to \text{m}=35:1000\text{m}=0.035\text{m} \\ p=15\text{cm}\to \text{m}=15:100\text{m}=0.15\text{m} \\ s=1\text{m} \\ x=a+2\cdot h+2\cdot p=1.2+2\cdot 0.035+2\cdot 0.15=\frac{157}{100}=1.57\text{m} \\ y=b+2\cdot h+2\cdot p=0.55+2\cdot 0.035+2\cdot 0.15=\frac{23}{25}=0.92\text{m} \\ y<s;x>s \\ z=x=1.57=1.57\text{bm} \end{gathered}$$
