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
1 answer:
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
