w= 1/2(L)
perimeter rectangle = w + w + L + L = 2w + 2L
54 = 2w + 2L
54 = 2 (1/2)(L) + 2L
54 = 3L
L = 18 cm
w= 1/2 (L) = 1/2(18) = 9 cm
perimeter rectangle = w + w + L + L = 2w + 2L
54 = 2w + 2L
54 = 2 (1/2)(L) + 2L
54 = 3L
L = 18 cm
w= 1/2 (L) = 1/2(18) = 9 cm
henry2,
Width = W.
Length = 2W.
2*W + 2*(2W) = 54
W = 9 cm = width.
Length = 2W = 18 cm.
Length = 2W.
2*W + 2*(2W) = 54
W = 9 cm = width.
Length = 2W = 18 cm.
