The width of a rectangle is 4 meters more then 1/3 its lenght. the perimeter is 64. Find the lenght and width

• algebra -

L = Lenght

W = Width

P = Perimeter

P = 64 m

W = 4 + L / 3

P = 2 * ( W + L ) = 64 m

64 = 2 * ( 4 + L / 3 + L ) Divide both sides with 2

32 = 4 + L / 3 + L

32 - 4 = L / 3 + L

28 = 4 L / 3 Multiply both sides with 3

28 * 3 = 4 L

84 = 4 L Divide both sides with 4

84 / 4 = L

L = 21 m

W = 4 + L / 3

W = 4 + 21 / 3

W = 4 + 7 = 11 m

Lenght = 21 m

Width = 11 m

P = 2 * ( W + L ) = 2 * ( 11 + 21 ) = 2 32 = 64 m
