Answer :
The length of the base of the triangle is 6 cm.
The given data of the triangle is as follows:
The area of the triangle = 38.4 cm squared
Height of the triangle = 12.8 cm
The formula for the area of a triangle is given:
Area of the triangle = (1/2) * base * height
Thus the formula for the base of the triangle will be:
Length of the base = ( 2 * area ) / height
Length of the base = (2 * 38.4) / 12.8
∴ Length of the base = 6 cm
From the above calculation and given values, the length of the base is found to be 6 cm.
