the length of a rectangle is 4 times its width. The rectangles perimeter is 68 feet what is the rectangles length and width ??
kodGreya [7K]

Answer:

Length = 27.2

Width = 6.8

Step-by-step explanation:

P = L+L+W+W

68 = 4(L+L)+W+W

68 = 4(x+x)+x+x

68 = 4x+4x+x+x

68 = 10x

x = 6.8

L = 4x

L = 27.2

W = x

W = 6.8

68 = 27.2+27.2+6.8+6.8

68 = 68
