Question

A design on the wall of room consists of 1000 tiles of the shape of parallelogram . If altitude and base of each tile is 10 cm and 4 cm , respectively find the cost of polishing the design at the rate of ₹ 9.50 square dm.<br />​

Answer 1

Answer:

Rs. 3800

Step-by-step explanation:

Area of the 1 parallelogram tile = altitude*base

= 10*4 = 40cm^2

Area of 1000 parallelogram tiles = 40*1000

=40000cm^2

40000cm^2 = 40000/100

= 400dm^2

Cost of polishing = 400*9.5

= Rs.3800
