Set an equation:

4/5=x-3/x+1
cross multiply

5x-15=4x+4

x=19

Width: 16 cm

Length: 20 cm

Find the perimeter and the area:

Perimeter: 16+16+20+20=72

Area: 20•16=320

Ratio: 320:72

Simplify the ratio:

40:9

Answer: The ratio of the area to the perimeter is 40:9.

Given that a room is shaped like a golden rectangle, and the length is 29 ft with the ratio of  golden rectangle being (1+√5):2, thus the width of the room will be:
ratio of golden triangle=(length if the room)/(width of the room)
let the width be x
thus plugging the values in the expression we get:
29/x=(1+√5)/2
solving for x we get:
x/29=2/(1+√5)
thus
x=(29×2)/(1+√5)
answer is:
x=58/(1+√5)
or
 byrationalizing the denominator by multiplying both the numerator and the denominator by (1-√5)
58/(1+√5)×(1-√5)/(1-√5)
=[58(1-√5)]/1-5
=(58√5-58)/4

The lenght of a rectangle is 2 units more than the width. The area of the rectangle is 48 units. What is the length, in units, o
LenKa [72]

Answer:

The length of this rectangle is 6 units.

Step-by-step explanation:

Let the width of the rectangle be x.

x • (x+2) = 48

x^2+2x=48

x^2+2x-48=0

x^2 - 6x + 8x - 48

x(x-6) 8(x-6)

(x+8)(x-6)

x=-8,6
