Lamonte has 50 m of fencing to build a three-sided fence around a rectangular plot of land that sits on a riverbank. (The fourth
Korvikt [17]

The dimensions of the length and width are 25 meters and 12. 5 meters respectively.

<h3>How to determine the values</h3>

Area of a rectangle

area of rectangle = l × w

where

l = length

w = width

Note that,

Perimeter = 2w+ l

50 = 2w + l

l = 50  - 2w

Hence,

area = w(50 - 2w)

288 = 50w - 2w²

-2w² + 50w - 288 = 0

-w² + 25w - 144 = 0

The dimension w can be found as follows;

w = - b / 2a

where

a = -1

b = 25

w = - 25 / 2 ×  -1

w = 12.5 meters

Then, we have that

l = 50  - 2w

Substitute the value of w

l = 50 - 2(12.5)

l = 50 - 25

I = 25 meters

Thus, the dimensions of the length and width are 25 meters and 12. 5 meters respectively.

Megan’s TV had a base price of $189 and the sales tax was 6. 88%. Over the next four years, the TV consumed an average of $0. 06
andreyandreev [35.5K]

Lifetime cost of Megan's TV is sum of base price, tax, electricity cost and repair cost. The lifetime cost of Megan’s TV is $347.

<h3>What is lifetime cost of a product?</h3>

Lifetime cost it the overall cost of the product, which is expend over it during its service including base price, service charge, fuel charge etc.

Given information-

The base price of the TV is $189.

The daily consumption of electricity by the YV is$0.06

The cost of repairs each time is $29.

As The base price of the TV is $189 and the sales tax on it was 6.88 percent Thus the total base price of the TV at the time of buy is,

C_b=189\times\dfrac{106.88}{100}\\C_b=202.0032

Thus, the total base price of the TV at the time of buy is $202.0032.

As The daily consumption of electricity by the YV is$0.06. Thus the total cost of electricity used by TV in four years (including one leap year) is,

C_E=0.06\times(3\times365+366)\\C_E=87.66

Thus the total cost of electricity used by TV in four years is $87.6.

As the cost of repairs each time is $29 and need to be repair it twice. The total cost of repair is,

T_r=29\times2\\T_r=58

Thus the total cost of repair the TV is $58.

As the lifetime cost of TV is the sum all the cost in 4 year service of TV. Thus,

C_T=202.0032+87.66+58\\C_T\cong 347

Hence,  the lifetime cost of Megan’s TV is $347. Option C is the correct option.
