Step-by-step explanation:
Assume breadth = x
Length = 2x + 5
Area = Length × Breadth
250 = (2x+5) × x
=> 250 = 2x^2 + 5x
=> 2x^2 + 5x - 250 = 0
=> 2x^2 + 25x - 20x - 250 = 0
=> x(2x + 25) - 10(2x + 25) = 0
=> (x-10)(2x+25) = 0
Either, x - 10 = 0
=> x = 10
or, 2x + 25 = 0
=> x = - 12.5 (Reject since x cannot be negative)
Breadth = 10 cm
Length = 2 × 10 + 5 = 25 cm
