The length of a rectangle measured with a 10 m chain was found to be 100 m. This chain was 10 cm too long. Also, during the measurement of breadth with a chain of 20 m length, the applied pull was 20 kg; whereas, the standard pull for the chain was 10 kg. The measured breadth was 50 m. Find the actual area of the rectangle in m². Modulus of elasticity of chain = 2 × 10⁶ kg/cm² and area of cross-section of chain is 0.05 cm².
