What is the area of the triangle?

So we know the formula for a triangle, is (base * height) / 2.

Base(6) * Height(2) / 2:

(6*2) / 2

12/2

6

Area of the triangle is (1/2)×base×height

Here, base = 6cm, height = 2cm

Area = (1/2) × 6 × 2 = 6cm²

incomplete question. how do you expect anyone to you when you do not post the question in its entirety?

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
