Which could be the area of the base of the triangular prism?     [Not drawn to scale]6 ft210 ft212 ft220 ft2
Alexus [3.1K]
For this case, the first thing we must observe is that the base of the prism is a triangle.
 The area of the triangle is given by:
 A = (1/2) * (b) * (h)&#10;
 Where,
 b: base of the triangle
 h: height of the triangle
 Substituting values we have:
 A = (1/2) * (4) * (3)&#10;&#10;A = 6 ft ^ 2
 Answer:
 
The area of the base of the triangular prism could be:
 
A = 6 ft ^ 2
