The scale of a map is 1: 200.Calculate the actual area of a triangular coffee field whose sides are 6cm, 8cm and 10cm on the map. (3 marks)
A map has a scale of 1 : 2500 and on it is square plot of land which has an area of 4cm². Calculate the actual area in hectares of the land. (3mks)Worked Answer:(a) A small field was surveyed and the measurements recorded in a surveyor’s field book as in the table below. (i) Using a scale of 1cm to 10m make an accurate drawing of the map of the field. (4mks)(ii) Find the area of the field. (3mks)(iii) Assuming that the baseline in (a) runs in a northern direction give the position of D relative to A using bearing and distance. (3mks)
Four points B, C, Q and D lie on the same plane. Point B is 42km due southwest point Q. Point C is 50 km on a bearing of S60oE from Q. Point D is equidistant from B, Q and C.(a) Using the scale: 1cm represents 10km, construct a diagram showing the positions of B, C, Q and D. (5mks)(b) Determine the
