The run on the other section if its rise is 2.8m is 6.44m
Shapes or figures are known to be similar if the ratio of their sides is equivalent.
The formula for calculating the slope is given asa;
Slope = rise/run
Let the run of the other section be x such that if the rise and run on one
section are, respectively, 3.0 m and 6.9 m and the rise of other section is 2.8m then;
3.0/6.9 = 2.8/x
Cross multiply'
3.0x = 6.9 * 2.8
3.0x = 19.32/3
x = 6.44m
Hence the run on the other section if its rise is 2.8m is 6.44m
