Answer:

18

Step-by-step explanation:

perimeter of the base = 4+4+5+5=18

the first box will make up the base of the prism

and perimeter is the sum of the sides of the shape

The perimeter of the base of the prism is 28 units. The base of the prism forms a rectangle.

How to calculate the perimeter of the base of a prism?

The perimeter of the base is the sum of all its sides.

I.e., Perimeter of the base = S1 + S2 + S3 + ...

Where S1, S2, and so on are the sides.

Finding the perimeter of the bases of the given triangular prism:

The prism has a base with sides,

S1 = 4 + 5

S2 = 5

S3 = 4 + 5

S4 = 5

So, its perimeter = S1 + S2 + S3 + S4

                            = 9 + 5 + 9 + 5

                            = 28 units.

We can also calculate it by using the perimeter of a rectangle since the prism has a rectangular base.

Therefore, the perimeter of the base of the prism is 28 units.
