Explanation:
Given : There are 12 square tiles .
To Find: What is the total width of the tiles
Solution :
Dimension of each square tile =
![6(4)/(5)=(34)/(5)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/y75n0ygr4z4xzmqoy1zwdf6chqkt2ilz4r.png)
Thus the width of 1 tile =
![(34)/(5)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/r7xm149g4c75mih0w2v2z3yko2g7mp1yvx.png)
So, total width for 12 tiles =
![12*(34)/(5)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/a0pb5cnrj0iyacj2ahkslerj07og7gdbhs.png)
=
![81.6](https://img.qammunity.org/2020/formulas/mathematics/middle-school/u8e2dohjz9i8icss64fprjn133vy1b6y8q.png)
Hence the total width of tiles is 81.6 inches or
![81(3)/(5)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/7u2rkdsb0ui892lk7yfqup0fa0i6okt406.png)
