The height of the envelope is 10. This is because you divide the area by 3. So, the missing side is 10 inches.

3+3=6
?+?+6=30
?=12
12+12=24
24+6=30
The other two sides are equal to 12

Well, to get perimeter, you add the length and width, and then multiply your answer by two. So:

Jerry-

13+12=25

25*2=50

Ruth-

14+11=25

25*2=50

So both rooms are equal.

Hope this helps!!

Please help with my algebra homework and explain if you can

balandron [24]

$A= \frac{1}{2} h (x+y)$

we have to solve for x , solving for x means , we have to isolate x one one side , by shifting all other variables to other side

$A= \frac{1}{2} h (x+y)$

Multiply both sides by 2

2A = h(x+y)

Divide both sides by h

2A/h = x+y

Subtract y from both sides

$\frac{2A}{h} -y =x$

$x=\frac{2A}{h} -y$
