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.

Answer 1

B= A-lw over 0.5h

Explanation:

Answer 2

A = lw + 0.5bh.
subtract lw from both sides
A - lw = 0.5bh
divide both sides by 0.5h
Answer: b = (a - lw)/0.5h
