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 equals LW + 0.5 b h. Solve for b.
A.) B=A/lw+0.5h
B.) B=A-lw/0.5h
C.) B=A-lw-0.5h
D.) B=A+lw+0.5h

Respuesta :

A = LW + 0.5bh
0.5bh = A - LW
b  = (A - LW) / 0.5h

Its B

Note to avoid ambiguity its better to put the A - LW in parentheses
