Answer:
see below
Step-by-step explanation:
The area is given by
A = l*w
A = (4x-1) ( 3x+6)
FOIL
first 4x*3x =12x^2
outer 6*4x = 24x
inner -1*3x = -3x
last -1 *6 = -6
Add together
12x^2 +24x-3x-6
12x^2 +21x-6
The base angles theorem converse states if two angles in a triangle are congruent, then the sides opposite those angles are also congruent. The Isosceles Triangle Theorem states that the perpendicular bisector of the base of an isosceles triangle is also the angle bisector of the vertex angle.

The greatest area he can fence is 64 ft².
In order to maximize area and minimize perimeter, we use dimensions that are as close to equivalent as possible. 32 feet of fence for 4 sides gives us 8 feet of fence per side. We would have a square whose side length is 8; the area would be 8*8 = 64.
