Emek and Luna followed an old treasure map through the forest until they reached a clearing with a shape drawn on the ground. The map said the treasure was hidden only at the place with a perimeter of 34 meters. They measured the sides of the clearing: 8 meters, 7 meters, 10 meters, and 9 meters. By adding all the side lengths, they found the perimeter was 34 meters. They knew they had found the correct spot and happily uncovered the hidden treasure.

Hint
Add all four side lengths together.
The treasure map said the correct clearing must have a perimeter of 34 meters. The sides of the clearing are 8 meters, 7 meters, 10 meters, and 9 meters. What is the perimeter of the clearing?
34 meters30 meters44 meters26 metersCorrect! 8 + 7 + 10 + 9 equals 34, so this is the treasure clearing.
Remember that perimeter is the total distance around the shape.
Next🎉 Congrats! You got this question!
Hint
Use the perimeter found in the story and add the extra length.
Emek and Luna measured another path around the clearing that was 6 meters longer than the original perimeter. What was the length of this new path?
Correct! The new path is 34 + 6 = 40 meters.
Start with the clearing's perimeter of 34 meters before adding 6 meters.
Next🎉 Congrats! You got this question!
Hint
Add the four side lengths and compare the result with 34 meters.
A different clearing has sides of 8 meters, 8 meters, 9 meters, and 9 meters. Would this clearing also match the treasure map's required perimeter of 34 meters?
Yes, because its perimeter is 34 metersNo, because its perimeter is 30 metersYes, because it has four sidesNo, because its perimeter is 40 metersCorrect! 8 + 8 + 9 + 9 equals 34, so it also matches the required perimeter.
Calculate the perimeter first, then compare it with the treasure map's number.
