2 sides of a rectangle are one length whilst the other two sides are a different length, for example 2 sides are 4cm long and the other 2 sides are 6cm long. This rectangle would have a perimeter of 20cm

As a regular hexagon has 6 equal sides, just multiply the length of the sides by 6

A pentagon has 5 sides, therefore 5 x 5cm will give you the perimeter
|
2 x 7 = 14
38 - 14 = 24 24 ÷ 2 = 12 |

A regular hexagon has 6 equal sides. To calculate the length of each side, divide the perimeter by 6
|
If a rectangle measured 7cm by 10cm its area would be 70cm2

Grams measure weight and millilitres measure volume. Square metres measure area but chocolate bars aren't that big!
|
10m2 would be large enough for a room in a house but not big enough for a classroom

Towns might be measured in km2, playgrounds in m2 and pen tips in mm2

There are 100cm in 1m so 100 x 100 = 10,000
