Answer:

option C

Step-by-step explanation:

area of rectangle = length * width

12x^2 - 5x - 3 = (4x - 3) * width

12x^2 - 9x + 4x - 3 = (4x - 3)* width

3x(4x - 3) + 1(4x - 3) = (4x - 3)*width

(3x + 1)(4x - 3) / (4x - 3) = width

3x + 1 = width

The perimeter of a rectangle is 16.6km, and its area is 13.42km2. Find its length and width. length : km width : km

Otrada [13]

Answer:

l=5.12 & w=2.62

Step by step explanation:

A=l×w

13.42=lw

w=13.42/l

$p = 2(l + w) \\ 16.6 = 2(l + \frac{13.42}{l} ) \\ 16.6 = 2( \frac{ {l}^{2} + 13.42}{l}) \\ 16.6 = 2(l + 13.42) \\ 16.6 = 2l + 26.84 \\ 2l = 26.84 - 16.6 \\ 2l = 10.24 \\ l = \frac{10.24}{2} \\ l = 5.12km$

Since you have found the value of the length you can find the value.of the width.

$w = \frac{13.42}{l} \\ w = \frac{13.42}{5.12} \\ w = 2.62km$
