1) Two metal strips are measured as 6.21cm and 1.529cm, correct to two and three decimal places respectively. Estimate their combined length when the strips are laid end to end. 2) A right-angled triangle has shorter side lengths exactly y^2 - x^2 and 2xy units respectively, where x and y are positive real numbers such that y is greater than x. Find an exact expression for the length of the hypotenuse (in appropriate units).
