Question

Identify the region that represents x${}^2$.

• A.
• B.
• C.
• D.

Answer 1

The correct option is D

The length of the green block is x and its width is y. So, its
area = xy. Hence, the region can be represented as xy.

The length of the purple block is y and its width is y. So, its
area = y${}^2$. Hence, the region can be represented as y${}^2$.

The length of the yellow block is y and its width is x. So, its area = xy. Hence, the region can be represented as xy.

The length of the blue block is x and its width is x. So, its
area = x${}^2$. Hence, the region can be represented as x${}^2$.
