Question

the length of a rectangle is twice its width.if it perimeter is 54 cm, find it's length​

Answer 1

Answer:

Perimeter of the rectangle - 54 cm. L+B = 54/2 = 27 cm. B = 27/3 = 9 cm. The length is 9x2 = 18 cm.

Answer 2

Answer:

Length of rectangle is 18 cm

Step-by-step explanation:

Length(l) = 2*Width(W)

Perimeter = 2(l +W)

54 = 2(l + W)

27= l + W

27 = l + 0.5l

27 = 3l/2

l = 18 cm
