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
