1.	The table top is in the shape of a trapezium with measurements given in the figure. Find the cost of the glass used to cover the table at the rate of Rs 6 per 10 sq. cm.
Answer» Length of the parallel sides a = 200 cm b = 150 cm Height h = 50 cm Area of the trapezium = \(\frac{1}{2}\) x h(a + b) sq. units = \(\frac{1}{2}\) x 50 (200+ 150) cm² = \(\frac{1}{2}\) x 50 x 350 cm² = 8750 cm² Cost for 10 sq. cm glass = Rs 68 ∴ Cost of 8750 cm² glass = \(\frac{8750}{10}\) x 6 = Rs 5250 Cost of glass used = Rs 5,250

The table top is in the shape of a trapezium with measurements given in the figure. Find the cost of the glass used to cover the table at the rate of Rs 6 per 10 sq. cm.

Answer»

Length of the parallel sides a = 200 cm

b = 150 cm

Height h = 50 cm

Area of the trapezium = \(\frac{1}{2}\) x h(a + b) sq. units

= \(\frac{1}{2}\) x 50 (200+ 150) cm²

= \(\frac{1}{2}\) x 50 x 350 cm² = 8750 cm²

Cost for 10 sq. cm glass = Rs 68

∴ Cost of 8750 cm² glass = \(\frac{8750}{10}\) x 6 = Rs 5250

Cost of glass used = Rs 5,250
