Question

a 2m wide path runs alng inside the boundary of a square field whose side measures 70m. the path is to be paved , and the rest of the field is to be manured. find the total expenses involved if paving costs rs 4.50 per sq m and maniring costs rs. 0. 75 per sq. m​

Answer 1

Answer:

Area of path = 70² - 66² = (70+66)(70-66) = 2176m²

Area of rest field = 66² = 4356m²

cost of maniring = 4356*0.75 = ₹ 3267

cost of paving = 2176*4.5 = ₹ 9792
