Question

Shelly's square garden has an area of 81ft (squaredi do not know how to do the symbol lol) what is the side of each length please help

Answer 1

`\textit{area of a square}\\\\ A=s^2~~ \begin{cases} s=\stackrel{side's}{length}\\[-0.5em] \hrulefill\\ A=\stackrel{ft^2}{81} \end{cases}\implies 81=s^2\implies √(81)=s\implies 9=s`

Answer 2

9 ft

Explanation:

area of a square = side length × side length = (side length)²

Given:

• area of square = 81 ft²
• side length = x

⇒ 81 = x²

⇒ x = √81

⇒ x = 9 ft
