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
