x^2 = 5 - x

x^2 + x - 5 = 0

-1 +/- $\frac{ \sqrt{ {1}^{2} - 4(1 \times - 5) } }{2}$

x = (1 + √21) / 2

x = (1 - √21) / 2

The ratio of the length of a rectangle to its width is 8 to 5. If the longer side of the rectangle is 20ft, what is the length o

choli [55]

Answer: The answer is 12.5 ft.

Step-by-step explanation: Given that there is a rectangle with ratio of its length to breadth 8 : 5. Also, the longer side of the rectangle is 20 feet. We are to find the length of the shorter side.

Let, '8x' and '5x' be the length and breadth of the rectangle respectively. Since length is the longer side, so we have

$8x=20\\\\\Rightarrow x=\dfrac{20}{8}\\\\\\\Rightarrow x=2.5.$

Therefore, width, length of the shorter side will be

$W=5x=5\times 2.5=12.5~\textup{ft.}$

Thus, the length of the shorter side is 12.5 ft.
