Irina18 [472]

----------------------------------------------------
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
$Width = \frac{20}{ \sqrt{5} }$

$Answer: \boxed {Width = \frac{20}{ \sqrt{5} }}$
