From a rectangle on the 7cm and 5cm sides, cut a square with a side of 4cm, find the area of the remaining figure?

First, determine the area of the rectangle by multiplying its length by width.

The area will be denoted by a capital S.

S rectangle = 7 cm * 5 cm = 35 cm2.

Next, we determine the area of a square (all sides of it are the same), which was cut from a rectangle.

S square = 4 cm * 4 cm = 16 cm2.

Now we find out the area of the figure that remains if we subtract the area of the square from the original area of the rectangle:

S of the remaining figure = 35 cm2 – 16 cm2 = 19 cm2.

To summarize: the area of the figure becomes only 19 cm2.
