Question

. A farmer has a triangular piece of land of area 150 m2
If fencing the 15 m side costs Rs. 225, what will be the cost of fencing the remaining land?
BO
15 m​

Answer 1

Answer:

Rs 675

Step-by-step explanation:

Assuming  triangular piece of land  is Right angle triangle

Then Perpendicular on 15 m side would be p

Area = (1/2) * Base * height

=> (1/2) * 15 * p = 150

=> p = 20

Hypotenuse² = Perpendicular² + Base²

=> Hypotenuse² = 20² + 15²

=> Hypotenuse² = 625

=> Hypotenuse = 25

Remaining two sides length = 20 + 25 = 45 m

fencing the 15 m side costs Rs. 225

1 m cost = 225/15 = Rs 15 per m

45 m cost = 45 * 15 = Rs 675

cost of fencing the remaining land = Rs 675
