### Math Textbook

Question 6:
Step 1: Find what makes 64, so 8x8=64
Step 2: Find what makes 8, 4x4=8
Step 3: Find what makes 4, 2x2,
Step 4: Circle the prime numbers

64 is a perfect square number because you can multiply 8 by it's self to make 64.
Another way of saying that is...the square root of 64 is 8, it is a whole number, so it is a perfect square.

The area: 64m². You have to remember to draw the "tickeys" to show that it is a "real" square.

Step 1: Find the square root of 28 900
Step 2: The square root will tell what the length and width is
Step 3: Add the side together to find the perimeter which is 680
Step4: Then, the teacher told the students to do two laps, so you would multiply 680 by 2
that will give you 1360m

a² + b² = c²

That formula means, that if you take the legs of the triangle, square them, then add them, you will find (c²) which is the hypotenuse². So if you have a right triangle, the legs² will equal the hypotenuse².
