The amount of gravel and the area it covers are examples of ratios.
A weight of 7 lb can cover 1 square foot, while 315 lb can cover an area of 45 square feet.
The relevant parameters are:

To find the number of pounds needed for 1 square foot , perform the following calculation:

Thus, we have:


Cross multiply

And divide both sides by 36

The area that 315 lb of gravel can cover is calculated as follows:
So, we have:


Cross multiply


And divide both sides by 252

Thus, 7 lb will cover
1 square foot
, and 315 lb will encompass an area of
45 square feet.

To address this issue, we will utilize the formula for determining the distance from a point to a line.
The formula is:
distance = | a x + b y + c | / sqrt (a^2 + b^2)
We have the line equation:
y = 2 x + 4
Rearranging it results in:
<span>y – 2 x – 4 = 0 -->
a = -2, b = 1, c = -4</span>
The coordinates given are:
(-4, 11) = (x, y)
Substituting into the distance formula:
distance = | -2 * -4 + 1 * 11 + -4 | / sqrt [(- 2)^2 + (1)^2]
distance = 15 / sqrt (5)
distance ≈ 6.7
<span>Thus, the tree is approximately 6.7 ft from the zip line.</span>
