b= 8 in is the base length of the triangle 12 in.
C b= 8 in.
Explanation:
Area of triangle can be calculated by using the formula [tex]1/2 \ b \times h[/tex] when the area of the triangle is 48 sq. in. It will be assumed that the triangle is an equilateral triangle
Here, if h = 12 in. then base can be calculated by-
[tex]48 = 1/2 \ b \times 12[/tex]
[tex]48 = 6 \times b[/tex]
[tex]48 / 6 = b[/tex]
[tex]8 = b[/tex]
Therefore, the base length is 8 in when the height of the triangle is 12 in and the area of the triangle is 48 in.
