Question

inside a rectangular Garden 24 metres long and 18 metre wide two m margin is left for planting Tulip flowers. if 4 tulip stems can be planted can be planted in 1m square and each Tulip stem costs rupees 30 find the total expenditure incurred

Answer 1

: Length of the garden = 24 m 

Breadth of the garden = 18 m 

Outer area of the garden = 24 x 18 = 432 m^2 

Width of the margin = 2 m 

Dimensions of the garden leaving the margin: 
Length = (24 - 2x2) = 20 m Breadth = (18 - 2x2) = 14 m 

Area of the garden leaving the margin = 20 x 14 = 280 m^2 

Area of the margin left for tulips = 432 - 280 = 152 m^2. 

4 tulip stems can be planted in 1 m^2. 

Number of tulip stems that can be planted = (152) / 4 = 38. 

Cost of each tulip stem = Rs 30 

Total cost = 30 x 38 = Rs 1140.
