3. Find the area of a parcel whose size is as shown in the figure (made up of rectangle ABCD and...

Therefore, the total area of the parcel is equal to the sum of the areas of the rectangle ABCD and the square CEMN: AD x AB + CE^2.

The formula for calculating the area of the rectangle ABCD is AD x AB, and the formula for calculating the area of the square CEMN is CE^2.

Once we have calculated the area of the rectangle ABCD and the area of the square CEMN, we can add them together to find the total area of the parcel.

The area of a square is calculated by squaring the length of one of its sides. In this case, the length of square CEMN is CE.

The area of a rectangle is calculated by multiplying its length by its width. In this case, the length of rectangle ABCD is AD and the width is AB.
