Akash travels 15 km distance on the first day, 14 km on the second
day, 13 km on third day an so on. Ajay travels 10 km distance on
the first day, 12 km on the second day, 14 km on third day and so
on. After how many days will they meet?
Answer:
Side of the square garden = 30 m and width of the path along the border = 1 m Side of square garden without path = 30 – (1 + 1) = 30 – 2 = 28 m Now Area of path = Area of ABCD – Area of EFGH = (AB x AD) – (EF x EH) = (30 x 30) – (28 x 28) = 900 – 784 = 116 m2 (ii) Area of remaining portion = 28 x 28 = 784 m2 The cost of planting grass in 1 m2 of the garden = Rs 40 The cost of planting grass in 784 m2 of the garden = Rs 40 x 784 = Rs 31,360Read more on Sarthaks.com - https://www.sarthaks.com/108047/a-path-1-m-wide-is-built-along-the-border-and-inside-a-square-garden-of-side-30-m
