The answer is 24.62. Hope this help
Well, let's first find our rate of bags to meters.
If 12 bags of plaster covers 54m^2, then we need to divide 54 by 12 to figure out how many meters 1 bag of plaster covers. We will then use that rate and divide 36 by it in order to solve for how many bags of plaster is required.
54 / 12 = 4.5.
This means each bag of plaster covers 4.5m^2.
Divide 36 by 4.5;
36 / 4.5 = 8.
This means that we will need 8 bags of plaster to cover 36m^2.
I hope this helps!

Let the width of the table be = x inches
As the length of a table is 16 inches more than its width, so length = x+16
Area of the rectangular table = 720 square inches
Area of rectangle = ![length*width](https://tex.z-dn.net/?f=length%2Awidth)
![720=x(x+16)](https://tex.z-dn.net/?f=720%3Dx%28x%2B16%29)
![720=x^{2}+16x](https://tex.z-dn.net/?f=720%3Dx%5E%7B2%7D%2B16x)
![x^{2}+16x-720=0](https://tex.z-dn.net/?f=x%5E%7B2%7D%2B16x-720%3D0)
![x^{2}+36x-20x-720=0](https://tex.z-dn.net/?f=x%5E%7B2%7D%2B36x-20x-720%3D0)
![x(x+36)-20(x+36)=0](https://tex.z-dn.net/?f=x%28x%2B36%29-20%28x%2B36%29%3D0)
![(x-20)(x+36)=0](https://tex.z-dn.net/?f=%28x-20%29%28x%2B36%29%3D0)
and ![x=-36](https://tex.z-dn.net/?f=x%3D-36)
Neglect the negative value as length and width cannot be negative
So, width = 20 inches
Length = x+16 = 20+16 = 36 inches
Hence, length is 36 inches and width is 20 inches.
