1. Problem Description

The problem asks us to identify which of the given shapes are rhombuses. We need to choose 2 answers. A rhombus is a quadrilateral (four-sided figure) with all four sides of equal length.

2. Solution Steps

Shape A has all sides equal to 9 m. Therefore, shape A is a rhombus.

Shape B has all sides equal to 5 m, and the angles are right angles. Therefore, shape B is a square. A square is a special type of rhombus.

Shape C has sides of lengths 4 cm, 3 cm, 4 cm, and 2 cm. Since the sides are not all equal, shape C is not a rhombus.

Since we need to choose 2 answers, we must choose the two rhombuses. Shape A is a rhombus. Shape B is a square, which is a special type of rhombus. Shape C is not a rhombus.

3. Final Answer

A, B
