Step-by-step explanation:
<h2>This is a monster question I don't think anyone solve it for only 5 points</h2>
The zeros of the function occur when the graph meet the x-axis so in this case the zeros occur at B ( 0 and 5)
Multiply both sides by 2 to cancel out the 1/2 and you get 2a=bh then divide both sides by h to isolate b and you get (2a)/h=b
