Answer» The garden is 26 m LONG and 14 m wide. So, the area of the garden = 26 × 14 = 364 m2 There is a path 2 m wide OUTSIDE the garden along its sides. Then, the NEW length of the garden with the path = 26 + 2 + 2 = 30 m. The new width of the garden with the path = 14 + 2 + 2 = 18 m. The area of the garden with the path along its sides = 30 × 18 = 540 m2 So, the area of the 2m wide path along the sides of the garden = 540 – 364 = 176 m2 The path is to be CONSTRUCTED with square marble tiles 40 cm × 40 cm = 0.40 m × 0.40 m. The area of one square marble tile = 0.40 × 0.40 = 0.16 m2 ∴ The number of tiles required to cover the path = 176/0.16 = 1100 |
