Which could be the area of the base of the triangular prism?
[Not drawn to scale)
• 6 ft²
• 10 ft²
• 12 ft²
• 20 ft²
Answer:
6ft²
Step-by-step explanation:
The formula for the base area of a triangular prism is given as:
Area of the base = √s(s-a) (s-b) (s-c)
Where s = (a+b+c)/2
From the attached diagram,
a = 5ft
b = 3ft
c = 4ft
s= (5ft + 3ft + 4ft) ÷ 2
s = 6ft
Area of the base = √ 6( 6-5) (6-3) (6-4)
= √6(1)(3)(2)
= √36
= 6ft²
Therefore, the area of the base of the triangular prism is 6ft²
