The length of rectangular garden is 6 feet longer than the width. If the area of the garden is 16 square feet, find the length a
Lyrx [107]

Length = x + 6

Width = x

Area = 16 ft^2

The formula needed is A = L•W.

Here is the set up:

16 = (x + 6)(x)

16 = x^2 + 6x

x^2 + 6x - 16 = 0

Solve for x. After finding x, plug into the definition I gave above for length and width to find your answer.

storchak [24]

Answer:

It would approximately be 3.73 m/h

Step-by-step explanation:

0.8 mins is 48 seconds

I then divided 8000 by 48 seconds to see how many cm it traveled per second.

It traveled 166.666666667 cm per second

I then converted cm to feet

so it was 5.468066491699474 feet per second

I then converted feet to miles, so it was 0.0010356186537309611598 miles per second.

Then I multiplied it by 60 so it was 0.06213711922 miles per minute.

Finally I multiplied it by 60 again to make it 3.72822715343 miles per hour.

I rounded it to the nearest hundredth making it 3.73 m/h
