Question

There are 4 cities placed on each corer of a square tha distance from one city to other is 8 km we had to construct a road connecting these cities we had only cash for making 22 km of road how can we construct the road

Answer 1

Answer:

it is said that each of these 4 cities lie on each corner of the square

the distance between each city is 8km.

since they only have enough cash for constructing only 22km.

The road can be constructed from city 1 to city3 diagonally and from city2 to city four diagonally both these roads should merge at the centre of the square .

the length of each road is approximately 11km.

proof: 8^2+8^2=root 128=length of one road.

+=2=2(11)                                      (since we know that both these  

  =22 km                                                   roads will merge we can take it as 11.)
