Assuming that this is a rectangle, you know that the length (longer side) would be 7cm, and the width (shorter side) would be 6cm. The formula for perimeter is, 2(length) + 2(width) = Perimeter Now we can plug in our numbers, 2(7cm) + 2(6cm) = 14cm + 12cm = 26cm The perimeter would be 26cm, assuming that this is a rectangle ^^

if you mean a rectangle: 8x2=16, that is 2 sides. 28-16=12cm 12/2 = 6cm so 8cmx6cm, if it is a rectangle

6cm + 6cm = 12cm
