Answer:
D,E
Step-by-step explanation:
I chose D and E because a square has 4 equal sides, so I looked for answer choices with 4x and since it is (x+8) I also looked for answers with that multiplied by 4, and 32 since 8 times 4 is 32. Hope this helped! if you are confused just comment on this and I will gladly help!

Answer:
3a by 4a
Step-by-step explanation:
For dimensions L and W, the area and perimeter are ...
A = LW = 12a^2
P = 2(L+W) = 14a
Using the second equation, we can find L:
L +W = 7a . . . . . divide by 2
L = 7a -W
Substituting into the area formula gives the quadratic ...
(7a -W)(W) = 12a^2
W^2 -7aW +12a^2 = 0 . . . . arrange in standard form
(W -3a)(W -4a) = 0 . . . . . . . factor (find factors of 12 that total 7)
Then we have the two solutions ...
W = 3a, L = 4a
W = 4a, L = 3a
The rectangle dimensions are 3a by 4a.

2A=h(a+b)
2A=ha+hb
2A-hb=ha
2A-hb/h=a
