Question

Rectangle ABCD is shown on the grid. What is the area of rectangle ABCD in square units? A) 6 B) 3 C) 2 D) 1

Answer 1

The area of rectangle ABCD in square units is C) 2.

Step-by-step explanation:

To determine the area of rectangle ABCD, we need to multiply the length and width of the rectangle. Let's denote the length as
`\( l \)` and the width as

`\( w \)`. Looking at the grid, we can observe that the length is 2 units, and the width is 1 unit. Therefore, the area
`\( A \)` can be calculated as
`\( A = l * w = 2 * 1 = 2 \)` square units.

The area of a rectangle is calculated by multiplying the length and width, and in this case, the area is found to be 2 square units. This corresponds to option C) 2. It's important to recognize that the units for area are always squared, as we are dealing with two dimensions—length and width. Therefore, the correct answer to the question is option C) 2.

In summary, the area of rectangle ABCD is 2 square units, and this is obtained by multiplying the length and width. Understanding how to calculate the area of geometric shapes is fundamental in mathematics and provides a quantitative measure of the space enclosed by the shape.
