The cost of fencing of a rectangular field at rupees 30 per metre is rupees 2400 if the length of the field is 24 metre than its breadth

breadth = 8, length = 32

perimeter = 2 x (length x breadth)

               = 2 x ((24 + b) + b))

               = 2 x (24 + 2b)

               = 48 + 4 b

48 + 4b meters costs rupees 2400  

each meter costs rupees 30

so,

30 x (48 + 4b) = 2400

1440 + 120b    = 2400

          120b    = 960

                b    = 8

the breadth is 8m, the length is 8 + 24 = 32m

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
