From a rectangle with sides of 11 cm and 8 cm, 2 squares with sides of 5 cm were cut out. find the area of the rest of the figure.

1. To complete this task, it is necessary to subtract the area of ​​two squares from the area of ​​the rectangle, as a result we get the remaining area. Then we find the area of ​​the original rectangle:
11 cm * 8 cm = 88 cm2.
2. Now let’s calculate the area of ​​one square with a side of 5 cm:
5 * 5 = 25 cm2.
3. Now let’s determine the area of ​​two identical squares if the area of ​​one is 25 cm2:
25 * 2 = 50 cm2.
4. Finally, subtract the area of ​​two squares from the area of ​​the original rectangle to obtain the area of ​​the remaining piece of the figure:
88 – 50 = 38 cm2.
Answer: The area of ​​the remaining part of the rectangle is 38 cm2.
