Suppose the length is L feet and the width is W feet. Then, Perimeter = 14 => 2*(L+W) = 14 or L+W=7 Also, Area = 12 => L*W=12 You could try trial and error to solve these two equations and in this particular case you will get to the answer quite quickly but for a more general method: L+W=7 => W=7-L Substituting in the second equation, L*(7-L)=12 or L^2 - 7L + 12 = 0 L^2 - 3L - 4L + 12 = 0 (L-3)*(L-4) = 0 so L=3 or L=4 But L>W and L+W = 7 so L > 3.5 so L= 4 => W=3 feet
Yes, but it can be hard to find. Some easier to find examples are: L(Dirac Delta(t-a))=e^(-a*s) L(u(t-a)*f(t))=(e^(-a*s))*L(f(t-a))
f = {n : n Î Z, n ≥ 12}
Length (L) x Width (W) = Area 2*L+2*W = Perimeter 48/W=L (solved for L) 2*48/W+2*W=32 (inserted L into perimeter equation) 48+W^2=16*W (quadratic equation or factor) W=12 or 4 Therefore L=4 when W= 12 or L=12 when W=4 Length (L) x Width (W) = Area 2*L+2*W = Perimeter 48/W=L (solved for L) 2*48/W+2*W=32 (inserted L into perimeter equation) 48+W^2=16*W (quadratic equation or factor) W=12 or 4 Therefore L=4 when W= 12 or L=12 when W=4

f=2e l=12 is the formula.
I'm guessing 12 Inches in a Foot.
