A rectangle mesures 3 cm by 6 cm Three of these rectangles are put together to make a larger rectangle. Work out the perimeter of this larger rectangle: It mesures three 3 cm tall rectangles that are both 6cm each and another one that is 6 cm tall.

Respuesta :

Answer: 45 cm

Step-by-step explanation:

Assuming the rectangles r put together as per the attached picture.

length = 6+3 = 9 cm

Width = 3+3 = 6cm

Perimeter = 2(l+w)

P = 3(9+6)

P = 3 * 15

P = 45 cm
