on map distance between two points is 15 cm. the real distance between them is 20 km. draw a diagonal scale of this map to read km and hectometer to measure upto 30km. show the distance 24.8 km on scale. please solve the problem.

fst you need to find the total length of the scale
which gonna be
l= RF x (maximum length you wanna mes.)
here RF is representative factor which is the ratio of dimensions on map to real dimensions
and then you need to construct a diagonal scale which looks like the above pinned image
divide the total length of scale into desired no of equal parts and then further divide the first division
so the proportionality don't change.
L proportional to (maximum length you wanna mes.))
L/n in cm proportional to (max)/n in Km
ie. per division represent this much distance in real
same for the further division.
follow the above pinned image, note the above image
is just a reference pic has nothing nothing to do with current problem
