What is the answer to this?

Step-by-step explanation:

Each of the four sides of this triangular prism has height 8 m and base 12 m.  The area of each face this thus A = (1/2)(base)(height), or

A = (1/2)(12 m)(8 m) = 48 m^2.   The total side area is thus 192 m^2.

This is the surface area.  If we want to include the base area, that would be another (12 m)^2 , or 144 m^2.

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
