The formula of a slope:
We have the points (2, 5) and (4, 10). Substitute:
This means that 2.5mm of rain falls every hour
Assume that the height, base and the hypothesis of the triangular ground is 5mt, 7mt and 8mt respectively:
Area of the triangular ground
= (5*7/2) m^2
=35/2m^2
=17.5m^2
Cost of the levelling ground
= Rs(17.5*10)
= Rs 175
The levelling ground costs 175Rs.
The answer is Line Segment SR.
Line Segments RX and TC have the same measurement, and has a right angle at point X, this proves that SR is equal to the measurement of ST.
