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 ^^

A 6cm X 2cm shape is a rectangle. Two sides are 6cm, and the other two are 2cm. Therefore, 6+6 + 2+2 = 16cm.
A square with a perimeter of 24 cm has an area of: 36 cm2
It has 2 sides of 5 cm and 2 sides of 6 cm so the perimeter is 22 cm
