10. Determine the area of a square with each side length

18. A floor mat for gymnastics is a square with a side length of 14m. What is the area of the floor mat in square meters?

21. Kate is going to put a patio in her backyard. The patio stones she is using each have an area of 1m2. She has created a rectangular design shown.

That's all the answers to questions 4, 9, 10, 18, and 21 hope this helps.

Pythagoras Questions:

1. Answer in a short paragraph and with diagrams

Answer: The pythagorean relationship is a2 + b2 = c2. That means that a2 (we'll say its 3) + b2 (we'll say its 4) should = c2 (we'll say its 5). It also says that a and b the legs should equal the hypotenuse 5.

2. Solve the missing side length

P. S. don`t forget to put your answer on to the triangle

3. Is this a right triangle PROVE IT!!!
