Answer to Problem 65PPS
The expression for the remaining area is
Explanation of Solution
Given information:
A square is cut off from the figure,
Formula used:
Area of a square with side s is given by
Factorization formula for difference of squares
Calculation:
Consider the given information that a square is cut off from the figure,
Recall that area of a square with side s is given by
Area of the square with side x is ,
And the area of the square with side 6 units that is cut off is,
Area of the remaining figure is calculated as,
Therefore, expression for the remaining area is
Recall factorization formula for difference of squares
Apply it,
Thus, the expression for the remaining area is
