We know that:
perimeter = (2 x width) + (2 x length)
Plugging in what we know to this equation:
40 = (2 x 8) + (2 x length)
40 = 16 <span>+ (2 x length)
</span>24 = <span>2 x length
</span>12 = length
The length of the room is 12 feet

Step-by-step explanation:
Calculation for At what price should the manager sell the book shelf
First step is to calculate the price increase using this formula
Price increase=Marks up percentage*Wholesale price
Let plug in the formula
Price increase=60%*$147.00
Price increase=$88.20
Now let calculate the price that the manager should sell the book shelf using this formula
Book shelf Price=Wholesale price+Price increase
Let plug in the formula
Book shelf Price=$147.00+$88.20
Book shelf Price=$235.20
Therefore the price that the manager should sell the book shelf is $235.20
Answer: length = 8 units
Width = 2 units
Step-by-step explanation:
Let the length of the rectangle be represented by L
Let the width of the rectangle be represented by W
The sum of 5 times the width of a rectangle and twice its length is 26 units. This means that
5W + 2L = 26 - - - - - - - - 1
The difference of 15 times the width and three times the length is 6 units. It means that
15W - 3L = 6 - - - - - - - - 2
The system equations are equation 1 and equation 2.
Multiplying equation 1 by 3 and equation 2 by 2, it becomes
15W + 6L = 78
30W - 6L = 12
Adding both equations,
45W = 90
W = 90/45 = 2
15W - 3L = 6
15×2 - 3L = 6
-3L = 6 - 30 = - 24
L = - 24/ -3 = 8
