What is the surface area of this triangular prism rounded to the nearest tenth? A) 48.6km2 B) 63.4 km2 C) 72.6 km2 D) 84.4 km2

Correct option B) .

Step-by-step explanation:

We have the following figure attached as shown below.

Now, this triangular prism have 2 similar right angled surfaces and 3 rectangular surfaces , Let's calculate area for all of them:

2 similar right angled surfaces

We know that area of triangle =

⇒

⇒

⇒

But there 2 such surfaces so ,

3 rectangular surfaces

Area of rectangle =

⇒

⇒

⇒

⇒

⇒

⇒

Total area =

Adding area of 2 similar right angled surfaces & 3 rectangular surfaces:

=

Correct option B) .
