Area (square mirror)=side²
Therefore:
side²=256 in²
side=√(256 in²)=16 in
Rectangular mirror:
width= square mirror width=side=16 in
length=(width + 2 in)=16 in + 2 in=18 in.
Area(rectangular mirror)=length x width.
Area (rectangular mirror)=(18 in)(16 in)=288 in².
Answer: the area of a rectangular mirror is 288 in².

Answer:
Perimeter = 21.58 units
Step-by-step explanation:
Perimeter of a polygon = Sum of measures of all sides of the polygon
Perimeter of the quadrilateral LEAP = PL + AE + EL + LP
= 4.47 + 4.47 + 6.32 + 6.32
= 21.58 units

Answer:
-4
Step-by-step explanation:
This looks like point-slope form, which I find personally hideous. Let's change it to slope-intercept form to ease my conscience. (remember that slope-intercept form is y=mx+b, where m=slope and b=y-intercept!)
y - 5 = -4(x-8)
y - 5 = -4x + 32
y = -4x + 37
It's in slope-intercept form now! And -4 looks to be our m.
<u>So the slope is -4.</u>
