Jovana was trying to find a formula for that perimeter with one side 8 yards longer than the other side using the area. In which step did she make a mistake? Step 1: a=x(x+8)=256 Step 2: 256/x=x+8 Step 3: p=2[x+(x+8)] Step 4: 1/2p=x=(x+8) Step 5: 1/2p= x+256/x Step 6: 1/2p-x=256/x Step 7: x[1/2p-1]=256 Explain her mistake. What is the correct formula?
