Question

the area of a window is 40 square feet. the length is the square root of 20 feet. what is the width of the window

Answer 1

----------------------------------------------------
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 = (20)/( √(5) )`


`Answer: \boxed {Width = (20)/( √(5) )}`
