1. what is the area of the lamp visited by Ram
2.what is the area of the lamp visited by Sanjay
3. what is the area of land visited by Ram(if x is equals to 2, y is equals to 3)
4.what is the area of land visited by Sanjay(if x is equals to 2, y is equals to 3)
5. what is the difference between their cost if the cost is rupees 1000 per m^2
please answer this​

Answer 1

Answer:

Step-by-step explanation:

1 The area of the lamp visited by Ram is { (15x^2 - 4y^2) × (15x^2 + 4y^2)}m^2

2 The area of the lamp visited by Sanjay is $(x+12y)^{2}$ m^2

3 If x = 2 , y = 3 , then the area of lamp visited by Ram is (15×4-4×4) × (15×4+4×4) = 44×76 = 3344 m^2

4  If x = 2 , y = 3 , then the area of lamp visited by Sanjay is (2+36)^2 = 1444 m^2

5 the difference area of the lamps is 3344 - 1444 = 1900

required cost is = 1900×1000 = 1900000 rupees
