Remark 
There are many ways you can set up the problem. The conventional way is to set up a % equation

Givens
Let x = the number in the entire class.
Let 80% of the class = 24

Argument
80% of x = 24 Change 80% to a fraction.
80/100 * x = 24  Divide by 100
0.8 x = 24           Divide by 0.8
x = 24 / 0.8
x = 30

There were 30 people in the class.

It’s asking for LATERAL surface area btw
lozanna [386]

Answer:

Lateral surface area = 826.5 m²

Step-by-step explanation:

Formula to calculate the lateral surface area of the triangular prism,

Lateral surface area of the triangular prism = Perimeter of the triangular base × Height

Perimeter of the triangular base = 6 + 11 + 12

                                                      = 29 m²

Height of the prism = 28.5 m

Therefore, lateral surface area of the prism = 29 × 28.5

                                                                        = 826.5 m²
