Question

Through a rectangular field of length 90 m and breadth 60m two roads are constructed which are parallel to the sides and cut each other at right angles through the centre of the fields if the width of each road is 3m find (1) the area covered by the roads (2) the cost of constructing the roads at the rate of rs 110 per sq. m

Answer 1

Area of each road = length * breadth
= (90*3)m^2
= 270m^2
Therefore area of two roads=
270m^2 +270m^2
=540m^2
Cost of constructing the road per Sq. m=
1 Sq. m costs = Rs. 110
540 Sq. m costs = Rs (540*110)
= Rs. 59400
Ans:- 1) area covered by two roads : 540m^2
2) cost of constructing 540 Sq. m of
Road : Rs. 59400
