The base of the prism is a 3:4:5 right triangle.
One of the legs is its base and the other is its height. (The longest side is the hypotenuse!)

The area of the triangular base is bh/2 = (9)(12) / 2. There are two of these.
There are also three rectangular sides on the prism.
Their dimensions are 9 by 20, 12 by 20, and 15 by 20.

You can do the arithmetic from here.
And the answer is 828cm ^2

Picture attached below
jekas [21]

Answer:

D. sin J = Cos L

Step-by-step explanation:

LK = √219² - 178² = 127.58

sin J = <u>LK/LJ</u> =127.58/219 = 0.58

Cos L = <u>Lk/LJ</u> = 0.58

sin L = 178/219 = 0.81

Cos J = 178/219 = 0.81

Tan J = 127.58/178 = 0.72

tan L = 178/127.58 = 1.40
