Given information
----------------------------------------------------
Area = 40ft²
Length = √20 ft
----------------------------------------------------
Formula
----------------------------------------------------
Area = Length x Width
----------------------------------------------------
Find Width
----------------------------------------------------
40 = √20 x width
Width = 40 ÷ √20
Width = 40 ÷ 2√5
Width = 20 ÷ √5
[tex]Width = \frac{20}{ \sqrt{5} } [/tex]
[tex]Answer: \boxed {Width = \frac{20}{ \sqrt{5} }}[/tex]
