Count the squares in the first two and check by multiplying the sides. Then use only the measurements for the rest. Area is always in square units.

A garden is 6 m by 4 m. How much fence goes round it, and how much ground is inside?

Fence (perimeter)

Ground (area)

Area of rectangles

15 and 28 square units; 48 m², 60 m², 81 m², 60 m². The garden: 20 m of fence (6 + 4 + 6 + 4) and 24 m² of ground (6 × 4).

The garden question is there on purpose. Area and perimeter are learnt together and confused together, and asking for both in one question is the quickest way to find out which one a child has.
