( w - 10 ) ( w - 10 ) = 0
width = 10

Answer:
C 340 square units
Step-by-step explanation:
Divide it into smallest pieces.
I see two rectangles that I'm going to do.
The long rectangle reading the paper from bottom to top is a 4 by (4+11+4) rectangle.
The wide rectangle reading the paper from left to right is a 24 by 11 rectangle.
We need to find the area of both of these rectangles and then just add them together to get the total area.
So first rectangle has area 4(19)=76 and the second rectangle has area 264. The sum of these two numbers are 340 square units.
Let the number of weeks needed be x
160 + 7x = 210 + 5x
7x - 5x = 210 - 160
2x = 50
x = 25
Ans: After 25 weeks.
