1.	The sides of a triangular field are in the ratio of 3:5:7 and its perimeter is 300m. Find the cost ploughing the field at the rate of ₹.500 per 2 . (Take √=1.73)
Answer» ₹12,97,500Step-by-step explanation:ratio of the sides of a triangle is 3:5:7let the proportion be X,=> the perimeter = 3x+5x+7x = 300M => 15x = 300m => x = 300/15 m => x = 20 m=> sides of the trianlge 3x=320M , 5x=520m, 7x=720m=> 60m, 100m, 140marea of the scalene triangle = where s = here, s = (60+100+140)/2 = 300/2 = 150=> Area, A = m² = m² = m² = 50310m² = 1500 = 15001.73 = 2595m²Given that cost of PLOUGHING = ₹500 / m²therefore, cost of ploughing 2595m² = 2595 * ₹500 = ₹12,97,500
