Marcie wants to enclose her yard with a fence. Her yard is in the shape of a rectangle attached to a triangle. The formula for the area of the enclosed space is A = lw + 0.5bh. Solve for b.

Respuesta :

[tex]A=lw+0.5bh\\\\lw+0.5bh=A\ \ \ \ |subtract\ "lw"\ from\ both\ sides\\\\0.5bh=A-lw\ \ \ \ |multiply\ both\ sides\ by\ 2\\\\1bh=2(A-lw)\ \ \ \ |divide\ both\ sides\ by\ "h"\\\\\huge\boxed{b=\frac{2(A-lw)}{h}}[/tex]

b =A-lw  divided by 0.5h
