Answer:
8 by 12 units
Step-by-step explanation:
Let w represent the width of the rectangle. Then the length is 1.5w. The perimeter is 4 more than 3 times this, so is (3(1.5w) +4) = 4.5w+4
The perimeter is given by the formula ...
P = 2(length + width)
Filling in the given values for the variables, we have ...
4.5w +4 = 2(w +1.5w)
4 = 0.5w . . . . . . subtract 4.5w and collect terms
8 = w . . . . . . . . . multiply by 2
length = 1.5×8 = 12
The rectangle is 8 units wide and 12 units long. The perimeter is 40 units.

well, the difference from 5600 to 4200 is 1400.
If we take 5600 to be the 100%, how much is 1400 off of it in percentage?
![\begin{array}{ccll} amount&\%\\ \cline{1-2} 5600&100\\ 1400&x \end{array}\implies \cfrac{5600}{1400}=\cfrac{100}{x}\implies 4=\cfrac{100}{x} \\\\\\ 4x=100\implies x=\cfrac{100}{4}\implies x=25](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bccll%7D%20amount%26%5C%25%5C%5C%20%5Ccline%7B1-2%7D%205600%26100%5C%5C%201400%26x%20%5Cend%7Barray%7D%5Cimplies%20%5Ccfrac%7B5600%7D%7B1400%7D%3D%5Ccfrac%7B100%7D%7Bx%7D%5Cimplies%204%3D%5Ccfrac%7B100%7D%7Bx%7D%20%5C%5C%5C%5C%5C%5C%204x%3D100%5Cimplies%20x%3D%5Ccfrac%7B100%7D%7B4%7D%5Cimplies%20x%3D25)
