A triangular tent has two identical triangular side panels, each with a base of 6 meters and height of 5 meters. The fabric required includes 10% extra material for stitching and cuts. If the fabric costs ₹200 per square meter, what is the total cost of the fabric used for both panels?
Show answer & explanation
Correct answer: D
Explanation
Base of each triangle = 6 meters, Height = 5 meters, Panels = 2, Extra = 10%, Cost = ₹200/m²
Area of a triangle = (1/2) × Base × Height
Area of one panel = (1/2) × 6 × 5 = 15
Area of two panels = 2 × 15 = 30
Including extra = 30 × 1.10 = 33
Total cost = 33 × 200 = ₹6600
