The problem asks to identify which of the given shapes are rectangles. We need to choose 2 answers. A rectangle is a quadrilateral with four right angles. This implies that opposite sides are equal in length and parallel.

1. Problem Description

The problem asks to identify which of the given shapes are rectangles. We need to choose 2 answers. A rectangle is a quadrilateral with four right angles. This implies that opposite sides are equal in length and parallel.

2. Solution Steps

Shape A: The shape has four right angles (indicated by the small squares) and opposite sides are equal (3 m and 7 m). Thus, it is a rectangle.

Shape B: All sides are equal (9 m), which means that it is a rhombus. However, there is no indication of the angles being right angles. So, it is not a rectangle.

Shape C: This is just a line segment. It's not a two-dimensional shape and therefore can't be a rectangle.

3. Final Answer

A
