Question

A 1.115 m long and 64 board known as two roads at right angles to anyone 2 m wide running parallel to its length and the other 2.5 M wide running parallel to its breadth find the cost of travelling abroad at rupees 60 per metre square to

Answer 1

Answer:

Rs. 23,100

Step-by-step explanation:

let,

ABCD is the rectangular field. and KLMN be two rectangular roads with width 2 m and 2.5 m

Rectangular field,

Length = 1.115 m, Breadth = 64 m

Area = ( 1.115 × 64) 7360 m²

Area of road ABCD = (1.115 × 2) = 2.23 m²

Area of road KLMN = (64 × 2.5) = 160 m²

here,

EFGH is common to both roads

Area of EFGH = (2 × 2.5) = 5 m²

Area of roads = (2.23 + 160) m² - 5

= 157.23 m²

now,

Total cost gravelling the roads = Rs. 157.23 × 60

= Rs. 943.38

so,

the cost of gravelling the roads at 60 per m² is Rs. 943.38
