Question

A sidewalk is built 12 bricks wide by laying each brick side by side.how many inches wide is this sidewalk is each brick measures 2 7/8 inches wide?

Answer 1

The sidewalk is 34.5 inches wide.

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

=
`(23)/(8) * 12`

=
`(276)/(8)`

=
`34.5\ inches`

Therefore, the sidewalk is 34.5 inches wide.
