Answer:

Step-by-step explanation:

Let L = 10

Let W = 10 (a square is a rectangle)

Original area = (LW) = 10*10 = 100

L increases by 20 percent:  

(1.2)(10) = 12

W decreases by 20 percent:

(0.8)(10) = 8

New area: (12)*(8) = 96

Percent change:New−OldOld∗100New−OldOld∗100

96−100100=96−100100=  

(−.04)∗100(−.04)∗100 = 4 percent decrease

Algebra

L = length

W = width

Area = (1)LW

Length increases by 20 percent, width decreases by 20 percent:

1.2L * 0.8W = (.96) LW

.96 is 4 percent less than 1

The area decreases by 4 percent.
