The Fenced Garden
Measure twice, pay three times!
Fruitville. Momo plants a garden.
Momo: My new garden! Perimeter to make the fence.
The Muddle Troll: Need a fence? Muddle Troll has the best!
Momo: He says it's shorter than it is! I know how perimeter works!
Perimeter is all sides
Add all sides up.
It's the total length.
That's perimeter.
Momo: So I measure every side and add them up!
The Muddle Troll: Gives 10 metres but only 9 are shown.
Momo: For a square, each side is 8 metres. 4 sides of 8 = 32 metres.
8 + 8 + 8 + 8 = 32
Add every side, no corners left out.
Momo's tip
Always measure every side.
No skipping, no corners.
Add all sides to find perimeter.
Momo: Always measure and add every side. No skipping, no corners!
Your turn, hero!
