Question 165662
P=2(L+W)  W=L-3 substituting W and P(given as 22ft) into the first equation we get 22=2(L+(L-3)  so 22=2(2L-3) distributing the right side of the equation we arrive at 22=4L-6. Add 6 and divide by 4 on each side of the equation and we get L=7   since L=7 then W=L(7)-3 so W=4

L=7
W=4
