Answer:
5 cm each side
Step-by-step explanation:
To find perimeter you need to add all your sides. Rectangles have 2 pairs of opposing sides which are exactly the same as the other side. If two sides are 6 each and the total is 22 then subtract what you know. Two sides are 6cm so 6(2) = 12 cm and subtract it from your perimeter (22 - 12 = 10 cm remaining and two sides remaining). Use the remaining to find how long each side is (10/2=5 cm).
