a rectangle has a perimeter of 446 feet. the rectangle has a length of (13x-1) feet and a width of (9x+4) feet. find the length and width if the rectangle answer

Answer 1

P=2(L+W)

= 2(13x-1 +9x+4)

= 2(22x+3)

= 44x +6 = 446

44x =446-6 =440

x=440/44 = 10

13x-1 = 130-1 = 129 feet Long

9x+4 = 90+4 = 94 feet Wide

2(129+94) = 2(223) = 446
