2. The Length Of A Swimming Pool Is 8m Lonfer Than Its Width And The Area Is 105m\Xb2

2. The length of a swimming pool is 8m lonfer than its width and the area is 105m²

Formula:

A = lw

Let x be the width

Let x + 8 be the length

105 = (x)(x+8)

105 = x² + 8x

-x² -8x + 105 = 0

(-x + 7)(x + 15) = 0

-x + 7 = 0 or x + 15 = 0

x = 7 or x = -15

\boxed{\boxed{width=7m, length = 15m}}
