b= 8 in is the base length of the triangle 12 in.
C b= 8 in.
Step-by-step explanation:
Area of triangle can be calculated by using the formula
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-




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.
