Question

A square corner of 16 square centimeters is removed from a square paper with an area of (9x) square centimeters. Which expression represents the area of the remaining paper shape in square centimeters?

a) (9x - 16)
b) (9x + 16)
c) (9x² - 16)
d) (9x² + 16)

Answer 1

The area of the remaining paper shape after removing a square corner is found by subtracting the area of the corner from the larger square, resulting in the expression (9x - 16) square centimeters.

Step-by-step explanation:

To find the area of the remaining paper shape after a square corner has been removed from a larger square paper, we need to subtract the area of the removed square corner from the area of the larger square. The area of the larger square is given as (9x) square centimeters, and the area of the removed square corner is 16 square centimeters. Therefore, the expression representing the area of the remaining paper shape is (9x - 16) square centimeters, which is option a).
