Answer 1

Let W be the width of the table top
Then, the length L = W + 2

Area of a rectangle is L*W

15 = L*W
15 = W*(W + 2)
15 = W² + 2W
W² + 2W - 15 = 0

@ValentinaT Factor the equation and solve for W. After that, don't forget to add 2 to the value of W to get the L, the length.

Answer 2

So you would get: [3. -5].

Answer 3

W = 3 or W = -5.

-5 is extraneous because length in this context cannot be negative.

The width of the table is 3. What would the length have to be? @ValentinaT
