Answer: 162
Step-by-step explanation:
So you will need to find the Markup. The original cost is $120.
- Divide the number by 100 is 1.2. $1.2 is 1% of the $120.
- Now times the number by 35. $1.2 x 35 is $42.
- Finally, add the number. 120 + 42 = 162.

The equation is incorrect, is that what you wanted to find out?
1.4 as a fraction is 1 4/10 (simplified to 1 2/5).
Let x = length of the park
Let y = width of the park
Because the area is 392392 ft², therefore
xy = 392392 (1)
Because three sides of fencing measure 5656 ft, therefore
2x + y = 5656 (2)
That is
y = 5656 - 2x (3)
Substitute (3) into (1).
x(5656 - 2x) = 392392
5656x - 2x² = 392392
2x² -5656x + 392392 = 0
x² - 2828x + 196196 = 0
Solve with the quadratic formula.
x = (1/2)*[2828 +/- √(2828² - 4*196196)]
= 2756.83 or 71.17
Answer:
The possible dimensions are 2756.8 ft and 71.2 ft (nearest tenth)
