Which could be the area of one lateral face of the triangular prism? 7.5 ft2 15 ft2 20 ft2 39 ft2

C.20 square ft

Step-by-step explanation:

We are given that

Height of triangular prism=6 ft

Rectangular  face of triangular prism is called lateral face of triangular prism.

Length of lateral face,l=8 ft

Breadth of lateral face,b==2.5 ft

We have to find the area of one of the lateral face of the triangular prism.

We know that

Area of rectangle=

Area of lateral face of triangular prism=square ft

Area of lateral face of triangular prism=20 square ft

Hence,option C is true.

i dont know i just need points

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
