Answer:
0 square feet.
Step-by-step explanation:
The original 12 by 5 rectangle has an area of 60 since we can multiply the length of the width which is 12 and 5.
The new rectangle's length is increased by 25% which we can solve by multiplying 12 by 1.25. (This is because in other words we are solving 125% of 12.)
12*1.25 = 15
The length can be solved by subtracting 20% of 5 which can be seen as 5*0.8(In other words we are solving for 80% of 5 since 100% - 20% = 80%)
5*0.8 = 4
Now solve for the new rectangle: 15*4 = 60
We can see that there has been no change in the rectangle's area so simply it has been changed by 0 square feet
