Answer:
The sidewalk is 34.5 inches wide.
Step-by-step explanation:
Given:
A sidewalk is built 12 bricks wide by laying each brick side by side.
Brick measures 2 7/8 inches wide.
Now, to find the width of sidewalk.
Width of brick = 2 7/8 = 23/8.
Number of bricks = 12.
So, the sidewalk = width of brick × number of bricks
= [tex]\frac{23}{8} \times 12[/tex]
= [tex]\frac{276}{8}[/tex]
= [tex]34.5\ inches[/tex]
Therefore, the sidewalk is 34.5 inches wide.
