Question

A house has square room with an area of ...What is the length of the side of the square room to the nearest tenth?A. 5.0 ftB. 11.2 ft C. 31.3 D. 62.5 ft

Answer 1

B. 11.2 ft

Step-by-step explanation

We have that the area of the square room is 125 square feet.

The area of a square is given as:

`A=L^2`

This means that to find the length of side of the square room, we have to find the square root of the area.

That is:

`\begin{gathered} L\text{ = }\sqrt[]{A} \\ L\text{ = }\sqrt[]{125} \\ L\text{ }\cong11.2\text{ ft} \end{gathered}`

That is the length of the side of the room.
