Question 957403: The length of a rectangle is 5 inches more than 3 times the width. If the perimeter is 26, find the length and width. Could you send the solution? Answer by macston(5194) (Show Source):
You can put this solution on YOUR website! P=perimeter=26; W=width; L=length=3W+5in
P=2(L+W)
26=2(L+W) Substitute for L
26=2((3W+5in)+W)
26=2(4W+5in) Divide each side by 2
13=4W+5in Subtract 5in from each side
8in=4W Divide each side by 4
2in=W ANSWER 1: The width is 2 inches.
L=3W+5=3(2in)+5in=11 in ANSWER 2: The length is 11 inches.
CHECK:
P=2(L+W)
26in=2(11in+2in)
26in=2(13in)
26in=26in
