Marcie wants to enclose her yard with a fence. Her yard is in the shape of a triangle attached to a rectangle.

Yard is shaped like a square and a triangle.
The area of this figure can be found by the formula A = (wh) + 0.5(bh). If Marcie wants the total area to be larger than a specified value, she can use the formula A > (wh)+ 0.5(bh). Rewrite this formula to solve for b. Show all steps in your work.



Answer :

A>wh+bh/2
multiply both sides by 2
2A>2wh+bh
subtract 2wh from boths sides
2A-2wh>bh
divide both sides by h
(2A-2wh)/h>b
