MIP2601 Maths assignment 4. Question 1 1.1 Clocks and hour glass (sand). 1.2 Back in the day many ancient and medieval people used something called the cubit as a unit of linear measurement. The cubit was based on the length of the arm from the elbow to the tip of the middle finger and was deemed the equivalent of 6 palms or 2 spans, exactly why it was used to measure short distances. 1.3 The temperature of boiling water at sea level boils at 100 ºC (212 ºF). No, the boiling water is not the same because the boiling point of water reduces by around 0.5 ºC for every 150 metres of elevation gain. 3.1 I think in order for the area to be 48 units², the length has to equal to 8 units and the width 6 units or length must be 12 units and the width 4 units. This is based on the area formula for rectangle (L x b) and properties of a rectangle. Therefore: A = L x b A = 8x 6 A = 48 units However, if we look at the perimeter formula for this question. It would look something like this: P = 2 (L + W) 48/2 = 2L + 2W/2 24 = L + W L + W = 24 Hence there is no combination. When the length and width is added it’s us 24 units and when the same values are multiplied, it gives us 48 units. Therefore, a rectangle with the area of 48 units² and perimeter of 48 units cannot exist.
