Length of the rectangle 11 cm, width 3X, find the perimeter of the rectangle.
The perimeter of a rectangle is calculated by adding its four sides that are equal two to two.
Perimeter = 2*Length + 2*width = 2*11cm +2*3Xcm = 22cm + 6*Xcm
Answer : perimeter = 22cm + 6*Xcm

Answer:
Perpendicular means that,second gradient equals to first one as:
So,conducting the second equation to the form y=mx+c: 3y= -2x-5
So it's gradient is
converting to
equals to 1.5 or at least
Y find the equation of the first line you've got to use the formula: y-y1=m (x-x1)
y-1=1.5 (x+6)
y-1=1.5x+9
<u>y</u><u>=</u><u>1</u><u>.</u><u>5x</u><u>+</u><u>10</u><u> </u>is the equation of the first line.
