Answer:

The area needed is 13,000 square feet.

Step-by-step explanation:

The total space (area) = area of the square + area of the two half circles

=> Total area = area of square + area of the circle (as adding the two halves makes a complete circle)

$i.e \\ total \: area \: = 51 \times 250 + \pi( {r}^{2} ) \\ total \: area \: = 12750 + \pi( {25.5}^{2} ) \\ total \: area \: = 12750+ 251 \\ total \: area \: = 13000 \: square \: feet$

If the function is y = 4.5x. Then the rate of change of the function expressed as a unit rate will be 4.5.

<h3>What is the linear system?</h3>

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

A bike rental company charges a fee per hour.

The charge, in dollars, is the same each hour.

The ordered pairs (3, 13.50) and (5, 22.50) represent the corresponding hours, x, and cost, y.

Then the linear equation is given as

$\begin{aligned} \rm y - 22.5 &= \rm \dfrac{22.5 - 13.5}{5 - 3} (x- 5)\\\\\rm y - 22.5 &= \rm 4.5x - 22.5\\\\\rm y &= \rm 4.5x \end$
