Find the area if this prism please

215 cm^2 (I'm sorry that it isn't an answer, but I assure you this answer is correct.)

Step-by-step explanation:

Multiply the side lengths of the rectangles together. The triangles are congruent so you can do the same thing to 1 of them.

5 x 13 = 65 (big rectangle)

5 x 13 = 65 (triangles)

5 x 12 = 60 (small rectangle)

5 x 5 =  25 (square)

65 + 65 + 60 + 25 = 215

Method two:

Everything has a width of 5, so add up the lengths and multiply by 5.

13 + 13 + 12 + 5 = 43

43 x 5 = 215
