Question 140597
Dividing the perimeter by 4? You have percentage of being right but not really the way to start it.
Okay,let's get the formula for perimeter first (P) = 2(L+W), right? This is equation 1.
Knowing the length(L) exceeds the width(W) by 53, so L=W+53, right? and mark this equation 2. Substitute this value to the 1st eq'n knowing the perimeter:
190=2(W+53+W)=2(2W+53)=4W+106
190-106=4W
84/4=W
21inches=Width
Go back eq'n 2: L=21+53
                L=74 inches. 
Simply to check if in doubt,
P=2(L+W)
190=2(21+74)=2(95)
190=190   cool!
thank you,
