A swimming pool is 25 m by 10 m. A tiled border 1.5 m wide is laid around it on the outside, at ₹80 per m². Find the cost of tiling.

Question

Accepted Answer

₹9,120. Outer: (25 + 3) × (10 + 3) = 28 × 13 = 364 m². Border = 364 − 250 = 114 m². Cost = 114 × 80 = ₹9,120. (₹8,400 uses 2 × (25 + 10) × 1.5 = 105 m² and misses the corners.)

A swimming pool is 25 $m$ by 10 $m$ . A tiled border 1.5 $m$ wide is laid around it on the outside, at ₹80 per $m^{2}$ . Find the cost of tiling.
