Answer 2

Answer:

Step-by-step explanation:

Answer:-

To answer this question, let me make the figure.

Now, we can easily solve the question, with a quick catch located in the middle part.

\boxed{\rm{Rectangular \ Area = Length \times Breadth}}

Rectangular Area=Length×Breadth

So,

Length is 90 m

Breadth is 60 m

\rm{Area = 90 \times 60}Area=90×60

\rm{Area = 5400 \ m^2}Area=5400 m

2

Calculating area of R1 now,

\rm{Area = 3 \times 60}Area=3×60

\rm{Area = 180 \ m^2}Area=180 m

2

Now, calculating area of R2,

\rm{Area = 3 \times 90}Area=3×90

\rm{Area = 270 \ m^2}Area=270 m

2

Catch Point:-

The middle area of both road is common in both. So, we will calculate that area, and subtract from any one road.

Area of Square = (side)²

= 3 × 3

= 9 m².

Now, subtracting 9 from 270, 261 cm² is the remains.

Now, (i) Area of Roads is 261 + 180 = 441 m²

(ii) the cost of constructing the roads at the rate of 110 per m²

This will be for 1 metre square. So, for 441, it will be

441 × 110

= Rs. 48510
