Question

I’m trying to make a study guide and need step by step explanation on how to solve this question please

Answer 1

Given:

The dimension of square shape floor is 200 feet by 200 feet.

The area of the square is calculated as,

`\begin{gathered} A=side^2 \\ A=200^2=40000 \end{gathered}`

Now, given that the 1/2 bottle will cover approximately 2000 quare feet.

It gives,

`\begin{gathered} (1)/(2)\text{ bottle=2000 square f}ee\text{t} \\ 1\text{ bottle=4000 square fe}et \end{gathered}`

So, the number of bottles required are,

`(A)/(4000)=(40000)/(4000)=10\text{ bottles}`

Answer: option B)
