Answer :
Answer:
[tex]a=\frac{2A}{p}[/tex]
Step-by-step explanation:
[tex]A=\frac{1}{2}ap[/tex]
To get rid of the fraction on the right, multiply both sides by 2.
[tex]2A=ap[/tex]
To separate a from p, notice they are "connected" by multiplication. Divide both sides of the equation by p.
[tex]\frac{2A}{p}=\frac{ap}{p}\\\frac{2A}{p}=a[/tex]
