What is the length of a rectangle with a width of 4 centimeters and a perimeter of 28 centimeters?

Length + Length + 4 + 4 = 28

2 Length = 20

Length = 10 cm < answer

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you
