Length = 12 m and width = 
m.
Solution:
Let the width of the rectangle be w.
Length of the rectangle = 2w + 5
Area of the rectangle given = 42 m²
<em>Area of the rectangle = length × width</em>
length × width = 42
(2w + 5) × w = 42
Subtract 42 from both sides, we get
Using quadratic formula,
Here, 
Dimension cannot be in negative, so neglect w = –6.
Width of the rectangle = m
Hence length = 12 m and width = m.
A) 38*(1-20%)*(1-10%)=27.36
b)38*(1-30%)=26.6
c)Because in question one when you take off the 10% it is 10% of the already off price but when you take off 30% it is taking off from the original price

Answer:
$ 1,559.935
Step-by-step explanation:
Given that the salesman receives 6.5% of total sale made as commission
Total amount of sale = $23999
Therefore, commission received by salesman = 6.5% of 23999
= (6.5/100)×23999= $ 1,559.935
