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) .

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
