## anonymous one year ago 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.

$A = lw+\frac{ 1 }{ 2 }bh$ and this is what your problem states, well the picture is just here for a reference of what's going on, although your problem just requires to solve for a variable :)

So lets have some fun with algebra! Any idea how to start?

The way we do algebra is, we basically do the opposite operation of what already exists, and when we do so, we must do it to both the left side and right side of the equal sign.

Hey, are you there?
