The dimensions for this rectangle are b= 30 ft and h=20 ft.
<h3>Perimeter</h3>
The perimeter of a geometric figure is the sum of its sides.
The question gives:
- the geometric figure - rectangle
- the total perimeter - 120 ft
Therefore for the perimeter, you have
P=
+ h+ h +h
P=2b+3h
2b+3h=120 (1)
From equation 1, you can write:
2b=120-3h
b=
b= 60 -
(2)
The area for the rectangle is given by A= bh. Therefore, by replacing (2) in the formula for rectangle area, you have:

The maximum area will be calculated from the derivation of the previous equation of area.

The maximum area can be found when the first derivative is equal to zero. Thus,
60-3h=0
-3h=-60 *(-1)
3h=60
h=20
Now, you know the height and from equation 2 (b= 60 -
) you can find the base.
b= 60 -
b=60 - 3*10
b=60-30
b=30

700<=560+0.08x
x is total sales $
the 560 is the constant weekly pay, since we're only calculating for one week.
we're adding 0.08x to account for the 8% of the total sales
solve it for x:
700-560 <= 0.08x
140 <= 0.08x
1750 <= x
or x >= 1750
meaning she needs $1750 worth of sales that week to earn atleast $700
as for C) just draw a number line with the number 1750 in the middle and the right shaded because it is 1750 or more.
