The simplest form of the fraction is 9/25
2 x 2 x 6 = 24ft²
1 x 2 x 12 = 24ft²
L=2W+2
W=(L-2)/2
A=LW, using W from above makes this
A=L(L-2)/2
2A=L^2-2L
L^2-2L-2A=0, given A=84
L^2-2L-168=0
(L-14)(L+12)=0, since L>0
L=14
The length of the rug is 14 ft
(W=(L-2)/2=6 ft)
The simpliest way to do this is to turn both fractions into decimals
7/10 goes to 0.7 and 2/5 goes to 0.4
then the equation would be 0.7x + 20 = 0.4
hope I've helped!
