Question

1. a square with side length 1 inch (marked “1 in” on the bottom and right side) and right angles at all four corners.

Explanation:

Step1: Identify the shape

The figure is a square with side length \( s = 1 \) inch.

Step2: Recall the area formula for a square

The area \( A \) of a square is given by the formula \( A = s^2 \).

Step3: Substitute the side length into the formula

Substitute \( s = 1 \) inch into the formula: \( A = (1)^2 \).

Step4: Calculate the area

\( (1)^2 = 1 \) square inch.

Answer:

The area of the square is \( 1 \) square inch.
