Question

Find the length of rectangular field , given that it's breadth is 50 metres and the cost of turfing it at rupees at rupees 41.25 per metre square is rupees 154687.50.

Answer 1

Breadth of the rectangle = 50 metres
Length of the rectangle  =  ?
Cost of turfing                =  154687.50
Rate of turfing                =   41.25 per m²
Area of the rectangle     =  154687.50÷41.25 = 3750 m²
Area of any rectangle    =   2(l+b)
                    3750          =   2l+2×50
                   3650           =   2l
                       l              =   3650÷2 = 1825 
Length of the rectangle = 1825 metres

Answer 2

Answer:

1825

Step-by-step explanation:

Breadth of the rectangle= 50m

Length of the rectangle= l

Cost of turfing= 154687.50

Rate of turfing= 41.25 per m²

Area of the rectangle= 154687.50÷41.25= 3750m²

Area of any rectangle=2(l+b)

3750= 21+2×50

3650= 2l

l= 3650÷2= 1825

l= 1825
