Question

through a rectangular field of length 100 m and breadth 50 m two roads are constructed which are parallel to sides and cut each other at right angles through the centre of the field. if the width of each other road is 4 m, find the area covered by the roads and the cost of constructing the roads at ®120 per m²​

Answer 1

Step-by-step explanation:

the length and the breadth of calculator with the area of the rectangle along with the four m a circumference is with this calculator to find the width m of the area of the rectangle

Answer 2

Answer:

Given length of field = 90 m

width of field = 60 m.

Area of field =90×60

Area =5400m

2

length of road GEFH = 90 m.

length of road ABCD = 60 m.

width of each road = 3m [Given].

Area of roads =ar(ABCD)+ar.(GEFH)−ar(LIJK)

=90×3+60×3−3×3

=270+180−9

Area of roads =441m

2

.

∴ Area covered by roads =441m

2

.

cost of construction of roads =441×10

Total cost =4410Rs.
