Answer:
The base of the triangle = 9inches
Step-by-step explanation:
Explanation:-
The area of the triangle = [tex]\frac{1}{2} bh[/tex] square units
Given area of the triangle(A) = 54 square inches
Given the height of the triangle (h) = 12 inches
now equating [tex]\frac{1}{2} b h = 54[/tex]
[tex]\frac{1}{2} b (12) = 54[/tex]
now simplification, we get
6 b = 54
Dividing '6' on both sides, we get
b = 9
The base of the triangle = 9 inches
Conclusion:-
The base of the triangle = 9 inches
