There ya go. Awesome job. :)

To determine if the answers are correct, let's solve the problems step by step:

4. To find the side length of a square with an area of 64 m², we need to take the square root of the given area.

The square root of 64 is 8.

So, the correct answer is B. 8 m.

5. To find the length of a rectangle with an area of 12 yd² and a width of 3 yd, we can use the formula:

Area = Length × Width

Substituting the given values, we have:

12 yd² = Length × 3 yd

To isolate the length, we divide both sides of the equation by 3 yd:

12 yd² ÷ 3 yd = Length

4 yd = Length

Therefore, the correct answer is B. 4 yd.

So, according to your responses, the answers you provided are correct.
