Answer:
Step-by-step explanation:
We can use the same method as in the last question, but this time subtracting the strip.
The strip goes around which removes 4 cm twice, so we can remove 4 x 2 = 8cm from the dimensions of 30cm x 20 cm.
The remaining area is:
A = 22 x 12
A = 264 centimeters squared
Solution: 264 centimeters squared
