So u can see a rectangle and a triangle
Area of the rectangle is 7 x 12 = 84ft
Area of the triangle= base x height divided by 2
So 6 x 12 = 72. 72/2 = 36ft
Then u add both areas
36 + 84 = 120ft

A sofa depreciates at 20% of its original value each year. If the sofa was $349 at its time of purchase, what is the value of th

klemol [59]

Answer:

$142.95

Step-by-step explanation:

Given Original value of the sofa = $349

Rate of depreciation each year = 20%

Number of years = 4

To find the value of the sofa after 4 years use depreciation formula:

If the constant decrease in population be R% per annum. Then the population after n years is $P \times\left(1-\frac{R}{100}\right)^{n}$

$349 \times\left(1-\frac{20}{100}\right)^{4}=349 \times\left(\frac{100-20}{100}\right)^{4}$

$=349 \times\left(\frac{80}{100}\right)^{4}$

$=349 \times\left(\frac{4}{5}\right)^{4}$

= 142.9504

= 142.95 (Nearest cent)

Hence, the value of sofa after 4 years is $142.95.
