Answer 1

To find the lateral area of the prism, we need to find the area of all four sides excluding the bases.

The formula for the lateral area of a rectangular prism is: Lateral Area = 2 * height * (width + length)

Lateral Area = 2 * 2 * (6 + 19)
Lateral Area = 2 * 2 * 25
Lateral Area = 100 m2

To find the surface area of the prism, we need to add the areas of the bases to the lateral area.

The formula for the surface area of a rectangular prism is: Surface Area = Lateral Area + 2 * (base area)

The base of the prism is a rectangle with dimensions 19m by 6m, so the base area is 19 * 6 = 114 m2.

Surface Area = 100 + 2 * 114
Surface Area = 100 + 228
Surface Area = 328 m2

Therefore, the correct answer is:

100 m2; 328 m2
