Question

welp pls.i’m so confused

Answer 1

Answer:

Length = 17 units

Width = 1 unit

Step-by-step explanation:

$A = l * b$

$17 = (2x+1) (x-7)\\17 = 2x^{2} -14x+x-7\\17 = 2x^{2} -13x-7\\2x^{2} -13x-7-17=0\\2x^{2} - 13x -24=0\\(2x+3) (x-8)=0\\x=-\frac{3}{2} or x=8$

but x cannot be negative because length and width cannot be negative;

$x\neq -\frac{3}{2} : x = 8$

Length:-

$=2x +1\\=2(8)+1\\=17units$

Width:-

$=x-7\\=8-7\\=1 unit$
