Answer:

width = 10 units and length = 20 units

Step-by-step explanation:

Let the width be w

so Length will be 2w

using the rectangle formula:

$\sf Perimeter \ of \ rectangle= 2L + 2W$

$\sf 60= 2(2w) + 2w$

$\sf 60= 4w + 2w$

$\sf 60= 6w$

$\sf w = 10 \ units$

Find length:

$\sf length = 2w$

$\sf length = 2(10)$

$\sf length = 20 \ units$

That technique for solving equations is: Whatever you do to one side of the equation, you have to do to the other side to preserve the equality The technique for solving inequalities is: Whatever you do to one side of the inequality, you have to do to the other side to preserve the inequality. the techniques are the same. The difference between solving equations and solving inequalities is: If you multiply or divide an inequality by a negative number, then the inequality reverses. !!!!!
