The cost of -1m-2- constructing the roads-Rs- -110-The cost of -441m-2- constructing the roads-Rs- -110-times 441-Rs- -48-510-Therefore- the cost of constructing the roads-Rs- -48-510-

The cost of $$1m^2$$ constructing the roads$$=$$Rs. $$110$$The cost of $$441m^2$$ constructing the roads$$=$$Rs. $$110\times 441=$$Rs. $$48,510$$Therefore, the cost of constructing the roads$$=$$Rs. $$48,510$$.

The cost of $$1m^2$$ constructing the roads$$=$$Rs. $$110$$
The cost of $$441m^2$$ constructing the roads$$=$$Rs. $$110\times 441=$$Rs. $$48,510$$
Therefore, the cost of constructing the roads$$=$$Rs. $$48,510$$.
