seventy five pounds
Step-by-step explanation:
because the colors make him heavy duh
if RD is 12cm so AR is 12cm too... since the R is placed in the middle and we can analyze too that the AD is 24cm since RD is 12cm and AR is 12cm so...
12+12=24
AR= 12cm
<em>Hope it helps...</em>

Answer:
The first side of the rectangle = 3 ft
The other side = 8 ft
Step-by-step explanation:
Let the one side of the rectangle = k feet
So, the other side of the rectangle = 4 ( First side) -4 = (4 k -4 ) ft
Now, the area of the given same rectangle = 24 sq ft
Area of the RECTANGLE = LENGTH x WIDTH
⇒ Area = k x ( 4k - 4)
or, k ( 4k - 4) = 24
![\implies 4k^2 - 4k = 24\\\implies k^2 - k = 6\\\implies k^2 - k - 6 = 0\\\implies k^2 - 3k + 2k - 6 = 0](https://tex.z-dn.net/?f=%5Cimplies%204k%5E2%20-%204k%20%20%3D%2024%5C%5C%5Cimplies%20k%5E2%20-%20k%20%3D%206%5C%5C%5Cimplies%20k%5E2%20-%20k%20-%206%20%20%3D%200%5C%5C%5Cimplies%20k%5E2%20-%203k%20%2B%202k%20-%206%20%3D%200)
or, k(k-3) +2(k-3) = 0
or, (k-3)(k+2) = 0
or, k = 3, or k = -2
As k = Length of the rectangle, so CAN NOT BE NEGATIVE.
⇒ k ≠ -2 , ⇒ k = 3 ft
So, the first side of the rectangle = k = 3 ft
The other side = 4 k - 4 = 4 (3) - 4 = 12 - 4 = 8 ft
