We calculate the area of ​​a rectangle with the equation

A = LW1/2
A = The area of a rectangle
L = the height of the triangle
W = the base of the triangle

If the equation is one unknown to solve them quickly .
A = 128sq.ft
L = ?
W = 2L

substitute values ​​into the formula

A = L W 1/2
128sq.ft = Lft. (2Lft) 1/2
128 = L²
L = √128 = 8√2

W = 2L = 28√2 = 16√2
