Question

A garden has an area of 286ft. It’s length is 9ft more than it’s width. What are the dimensions of the garden?

Answer 1

Answer:

13

Step-by-step explanation:

• x × (x + 9) = x² + 9x = 286
• x² + 9x - 286 = 0
• (x - 13)(x + 22)
• x = 13 or -22
• Since you cannot have negative length, it’s 13
