A rectangle garden plot of size 240m × 150 m is having two cross roads, each 6 m wide running through its middle one is parallel to the length and other is parallel to the breadth. Find the total cost of paving the roads at the rate of Rs. 20 per sq. m and levelling the remaining area .

$\huge{\mathcal{\underline{\green{ANSWER}}}}$

Given,

A rectangular lawn 60 meters by 40 meters has two roads each 5 meters wide running in the middle of it one parallel to length and the other parallel to breadth

Area of the road $= 40 \times 5 + 60 \times 5 - 5 \times 5$

$= 200 + 300 - 25$

$= 475sqm$

Given,

Cost of graveling the roads =60 paise per sq meter.

$475 \times 60paise$

$= 28500 \: paise$

$= ₹285$

Answer 2

Given,

A rectangular lawn 60 meters by 40 meters has two roads each 5 meters wide running in the middle of it one parallel to length and the other parallel to breadth

Area of the road = 40 \times 5 + 60 \times 5 - 5 \times 5=40×5+60×5−5×5

= 200 + 300 - 25=200+300−25

= 475sqm=475sqm

Given,

Cost of graveling the roads =60 paise per sq meter.

475 \times 60paise475×60paise

= 28500 \: paise=28500paise
