Question

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.

b = A divided by the quantity l times w plus 0.5 times h
b = The quantity A minus l times w all divided by 0.5 times h
b = A – lw – 0.5h
b = A + lw + 0.5h

Answer 1

i will give medals and fan

Answer 2

\[A = lw +0.5bh\]
subtract lw from both sides
\[A - lw = 0.5bh\]
Divide both sides by 0.5h
\[A - lw / 0.5h = b\]

Answer 3

Both A - lw are over 0.5h
