A pair of perpendicular lines would be line CF and line AJ.
Line BC and line AJ are NOT perpendicular because when a pair of lines are perpendicular, all angles become 90 degrees. It is obvious, in the case, if you were to slide line BC on top of line AJ, the angles will not equal 90 degrees.
Okay, so you know that the perimeter of the pen is 28 feet. Now we need the separate side lengths.
P = 28 ft.
Length = x
Width = (1/2)x + 2
So now we can plug in the little equations of length and width into a perimeter formula:
2(x) + 2((1/2)x + 2) = 28
Distribute the 2's and solve as needed.
2x + x + 4 = 28
3x + 4 = 28
3x = 24
x = 8
To find the width, just plug in 8 for x in our little equation:
(1/2)(8) + 2
= 6
So, the length is 8 feet and the width is 6 feet.

<em>solution</em>
<em> time taken=100secs</em>
<em> distance covered=500m=0.5km</em>
<em>As we know,</em>
<em> speed=distance covered/time taken</em>
<em> =0.5km/100secs</em>
<em> =0.005km/sec</em>
<h2>
<em> </em></h2><h2>
<em> SPEED IS 0.005KM/SEC</em></h2>
5:3 = 120 : x
