Question

A walkway is being constructed using square cement tiles that each have an area of 19.0 ft2. 6 tiles will be lined up end to end to construct the walkway. What is the total length of the walkway? Round your answer to the nearest tenth of a foot. Your Answer:

Answer 1

26.3 feet

Explanation:

We have to first find the length of the side of each tile.

The area of each tile is 19.2
`ft^2`.

The area of a square is:

A =
`L^2`

where L = length of side

Therefore:

`19.2 = L^2\\\\L = √(19.2) = 4.38 feet`

6 tiles will be lined end to end to construct the walkway, hence, the length of the walkway is:

6 * 4.38 ≅ 26.3 feet
