Textbook Problem

The area of an enclosed plot of ground that a farmer has subdivided can be found by multiplying ( x + y ) times ( y + z ) . Use FOIL to complete the multiplication. How does this product compare with the total of the areas of the four smaller plots? To determine

To find:

The area of the enclosed plot of ground using FOIL method.

Explanation

1) In FOIL method, First, Outside, Inside, and Last pairs of terms are multiplied and then added.

2) The area of the rectangle is given by LW where L is the length and W is width of the rectangle.

Calculation:

It is given that the area of the enclosed plot is (x+y) times (y+z).

Apply FOIL to multiply (x+y) by (y+z)

(x+y)(y+z)
