a triangle has an area of 38.4cm. the height of the triangle is 12.8cm. what is the length of the base of the triangle

Answer: 6 cm

Step-by-step explanation:

Use equation for area of triangle

A=a*h/2

a*h=2A

a=2A/h

where a represents base of triangle

h represents height of triangle.

h=12.8 cm

A=38.4 cm²

a=2A/h=2*38.4 cm²/12.8 cm=76.8cm²/12.8cm = 6 cm
