In KS2 Maths, children learn about perimeter and area. In Year Five, they figure out how to find the perimeter of squares and rectangles. Now, they also explore other shapes like pentagons or hexagons and learn to calculate their area. Kids become confident with areas of squares and rectangles, understanding that square metres have 10,000 square cm, and square cm have 100 square mm.
The perimeter is the distance around a shape. To find a hexagon's perimeter, multiply one side's length by 6. For example, if the sides are 2 metres long, the perimeter is 12 metres. Area is like the size of a surface, important for planning how much paint a wall needs. Can you figure out the perimeter of a hexagon?

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
