Answer:

<em>82.67% of the fertilizer will be used on the property.</em>

Step-by-step explanation:

<u>Area of Plane Figures</u>

The backyard described in the problem has two parts: One with a rectangular shape of 30 feet by 20 feet. The other with a triangular shape with a base of 24 feet and a height of 12 feet.

The area of a rectangle is calculated by:

$A_r=L*W$

And the area of a triangle is:

$\displaystyle A_t=\frac{B*H}{2}$

All the backyard will be covered by fertilizer coming from a container with a capacity of 900 square feet.

The total area of the backyard is the sum of the area of the rectangle Ar and the area of the triangle At as follows:

$A_r=30*20=600\ ft^2$

$\displaystyle A_t=\frac{24*12}{2}=144\ ft^2$

The total area of the backyard is:

$A=600\ ft^2+144\ ft^2=744\ ft^2$

To find the percentage of the container, we calculate:

$\displaystyle \frac{744}{900}*100\%=82.67\%$

82.67% of the fertilizer will be used on the property.

Answer:

54 millimeters

Step-by-step explanation:

The median length would be in the middle of the values in order, so you could order the numbers 50,50,52,53,54,55,55,55,57. You would then find the middle value which would be the 5th value in a list of 9. In this case, it would be 54 millimeters.
