Answer:

<em><u>2</u></em><em><u>1</u></em><em><u>y</u></em><em><u>d</u></em><em><u>^</u></em><em><u>2</u></em>

Step-by-step explanation:

join the centre to all the vertex,

since this figure is of regular pentagon, it's will form 5 equal triangle of equal area!

now area of one such triangle is

1/2 ×base ×height

=1/2 ×3.5x2.4 (yd^2)

=4.2 yd^2

now the pentagon is sum of 5 such equal triangle,so it's are will be

5×4.2 (yd^2)

=21 yd^2

VashaNatasha [74]
The cost equation has a constant rate of change, so this is a line of the form:

y=mx+b, you are told that there is a flat fee of $5 and an hourly rate of $2 so

y=2x+5

The y-intercept (the value of y when x=0) is 5.  The point (0,5) on the line.
