Answer:
$357
Step-by-step explanation:
We have a rectangle measuring 25 feet × 9 feet. Remove from the rectangle two regular hexagons with a side length equal to 2 feet.
The formula of an area of a rectangle:
[tex]A_r=lw[/tex]
l - length, w - width.
Substitute l = 25 ft and w = 9 ft:
[tex]A_r=(25)(9)=225\ ft^2[/tex]
The formula of an area of a regular hexagon:
[tex]A_h=6\cdot\dfrac{a^2\sqrt3}{4}[/tex]
a - side
Substitute a = 2 ft:
[tex]A_h=6\cdot\dfrac{2^2\sqrt6}{4}=6\sqrt3\ ft^2[/tex]
The area of the wall:
[tex]A=A_r-2A_h[/tex]
Substitute:
[tex]A=225-2(6\sqrt3)=225-12\sqrt3\approx225-20.785=204.215\ ft^2[/tex]
Paiting the wall costs $1.75 per ft². Calculate:
[tex](\$1.75)(204.215)\approx\$357[/tex]
