Question

The length of a rectangle is 6 cm. If width is 2 /3 of its length, find the perimeter of the rectangle.
​

Answer 1

Answer:

length = 6 cm

width = (2/3)*6 = 12/3 = 4 cm

perimeter of rectangle = 2(l+b)

= 2(6+4)

= 2*10

20cm

Answer 2

Answer:

Length of rectangle = 6cm

Width of rectangle = 2/3 × 6  ⇒  4 cm

Perimeter of a rectangle = 2 × (Length + breadth)

⇒ 2 × (4+6)

⇒ 2 × 10

⇒ 20 cm

Therefore the  perimeter of the rectangle is 20cm.
