Answer:
The equivalent ratios are:
s = \frac{LA}{r}s=
r
LA
r = \frac{LA}{s}r=
s
LA
The formula LA = rsLA=rs is given
In order to determine the equivalent ratios, make r the subject of the formula and s the subject of the formula in the above equation
To make s, the subject of the equation, divide both sides of the equation by r
s = \frac{LA}{r}s=
r
LA
To make r, the subject of the equation, divide both sides of the equation by s
r = \frac{LA}{s}r=
s
LA

Thank's………………………………………………
Let the length be x and the width be y, then
2x + 2y = 56
x + y = 28 . . . (1)
x = 4 + 3y . . . (2)
Putting (2) into (1) gives
4 + 3y + y = 28
4y = 28 - 4 = 24
y = 24/4 = 6
x = 4 + 3(6) = 4 + 18 = 22
Therefore, length is 22 inches and width is 6 inches.

I also put this on your last post
About 176.4 is what i had gotten but i would still check out the other persons answer and compare
B. because when you write the ratio as 42:38, you can simplify it by dividing by 2. After that, you can't divide 21:19 evenly, so that is the simplest form.
