Answer: There is 14 yards of fabric he should buy.
Explanation:
Since we have given that
Dimensions of a table cloth needed is as follows:
Length = 8 feet
Width = 12 feet
Since we must add an additional 6 inches on each side .
So, Length becomes = 8 feet + 6 inches
As we know that
1 feet = 12 inches
So, length becomes = 8×12+6=96+6=102 inches
Similarly, width becomes = 12 feet + 6 inches = 12×12+6=144+6=150 inches
So, total length of fabric he should buy is given by
![2(length+breadth)\\\\=2(102+150)\\\\=2* 252\\\\=504\ inches](https://img.qammunity.org/2020/formulas/mathematics/middle-school/ggh0x5wq359wihe68zyos92y209fdzig9d.png)
So, Total length of fabric in feet becomes,
![(504)/(12)=42\ feet](https://img.qammunity.org/2020/formulas/mathematics/middle-school/e3gtfpqly5l1g31ktlyqivyju4bgtlcfcf.png)
Total length of fabric in yards becomes,
![(42)/(3)=14\ yards](https://img.qammunity.org/2020/formulas/mathematics/middle-school/dac7pvkayx4ryschdlhrf3u8qqu6nq91jj.png)
Hence, there is 14 yards of fabric he should buy.
