The perimeter of a rectangle is twice the sum of its length and it’s width . The perimeter is 22 meters and I it’s length is 2 m

lukranit [14]

Answer:

The length of this rectangle is 8m.

Step-by-step explanation:

The problem states that the perimeter of a rectangle is twice the sum of its length and it’s width. So

$P = 2*l + 2*w$

The problem also states that the perimeter is 22 meters. So:

$P = 22$

$2l + 2w = 22$ .

Also, it states that I is the length and it is 2 meters more then twice it’s width. So

$l = 2w + 2$

What’s its length?

$P = 22$

$2l + 2w = 22$

$2(2w+2) + 2w = 22$

$4w + 4 + 2w = 22$

$6w = 22 - 4$

$6w = 18$

$w = \frac{18}{6}$

$w = 3$

The width is 3m. The length is in function of the width, so:

$l = 2w + 2$

$l = 2*3 + 2$

$l = 8m$

The length of this rectangle is 8m.

How Do I Solve 3/2y= 16/y+2

IceJOKER [234]

$\frac{3}{2y}=\frac{16}{y+2}\ \ \ \ \ \ |cross\ multiply\\\\16\times2y=3(y+2)\\\\32y=3y+6\ \ \ \ \ |subtract\ 3y\ from\ both\ sides\\\\29y=6\ \ \ \ \ \ \ |divide\ both\ sides\ by\ 29\\\\\boxed{y=\frac{6}{29}}$

Marina CMI [18]

Answer:

$\boxed{w = 14.9} \: or \: you \: can \: say \: \underline{\boxed{w = 15} }$

Step-by-step explanation:

$applying \: the \: pythagorean \: rule : \\ {(hyp)}^{2} = {(adj)}^{2} + {(opp)}^{2} : \\ {w}^{2} = {11}^{2} + {10}^{2} \\ {w}^{2} = 221 \\ w = \sqrt{221} \\ \boxed{w = 14.866068747}$
