Question

Can anyone help me? I need step by step

Answer 1

Length is increased so the new length would be 1.1L

The width is decreased by p percent, which now becomes 1-P/100

The new area = 1.1l x (1-P/100)

The area decreases by 12 percent, so the new area = 0.88A

Noe you have 0.88A = 1.1L * (1-P/100)

Simplify to get 0.8 = 1-P/100

Solve for P to get 0.2

Multiply by 100 for the percent: 20%

The answer is C.
