Formula to find height when given diameter and slanted height

First find the radius
24÷2=12
Next square the radius
12²=144
Next square the slanted height
20²=400
Now find the square root of both

=16ft
Let the width be w
Width = w
Length = w + 6
Area = a
a = w(w + 6)
a = w² + 6w
Answer: a = w² + 6w
