Quadratic function and equation in one variable

Question

Azri wants to fence his garden with wire fences. He bought 3 rolls of wire fences with a length of each roll of 45 m. Given the area of the garden is 675 m². If the length of the garden is 30 m more than its width, is the wire bought sufficient to fence the garden?

Answer 1

Well, we know that in total, Azri has 135m of fencing to work with. If the length of the garden = 30 + width, and the area is l x w = 675, how might you be able to determine the length and width of the garden? Consider substitution.
