A piece of strings is \(30\) cm long. What will be the length of each side if the string is used to form: (1) A square? (2) an equilateral triangle? (3) A regular hexagon?
(1)c Perimeter of square \(= 30\) cm \(4 × side = 30\) Side \(= 30 / 4\) Side \(= 7.5\) cm (2)Perimeter of an equilateral triangle \(= 30\) cm \(3 × side = 30\) Side = 30 / 3 Side = 10 cm (3)Perimeter of a regular hexagon \(= 30 \) cm \(6 × side = 30\) Side \(= 30 / 6\) Side \(= 5\) cm

A contractor plans to install two slides for the children to play in a park. For the children below the age of \(5\) years, she prefers to have a slide whose top is at a height of \(1.5\ m\), and is inclined at an angle of \(30^o\) to the ground, whereas for elder children, she wants to have a steep slide at a height of \(3\ m\), and inclined at an angle of \(60^o\) to the ground. What should be the length of the slide in each case?
