Lelu [443]

Answer:

(x + 5) m

Step-by-step explanation:

From the question given above, the following data were obtained:

Area (A) = (x² + 8x + 15) m²

Width (W) = (x + 3) m

Length (L) =?

The lenght of the rectangle can be obtained as follow:

A = L × W

x² + 8x + 15 = L (x + 3)

Divide both side by x + 3

L = x² + 8x + 15 / x + 3

L = (x + 5) m

Please attached photo for explanation.

Therefore, the length of the rectangle is: (x + 5) m
