Algebra 2 Linear Equations w/ One variable The Kahn Family lives in a house that has a backyard in the shape of an isosceles trapezoid and a triangle. The area of the backyard can be expressed as the sum of the area of the triangle and the area of the trapezoid, which is \frac{\mathbf{1}}{\mathbf{2}}\mathbit{bh}+\frac{\mathbf{1}}{\mathbf{2}}\left(\mathbit{p}+\mathbit{q}\right)\mathbit{l}. The base and the height of the triangle are represented by \mathbit{b} and \mathbit{h}, respectively. The bases of the trapezoid are \mathbit{p} and\mathbit{q}, and the height of the trapezoid is L.

Rearrange the formula to find the length of the base\mathbit{l} as a function of the lengths of the other sections of the backyard.


b=\frac{2A-(p+q)L}{H}
