Question

Marcie wants to enclose her yard with a fence. your 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

Area = LW + 1/2 b * h Subtract L*W from both sides.

Area - LW = 1/2*b*h Multiply both sides by 2

2*Area - 2*LW = b*h Divide by h

`\text{b} = (2*A - 2LW)/(h) =(2A )/(h) -(2LW)/(h)`
