Answer 5

Remember that the area formula of a square is \[Length \times Width\]

Answer 6

6*5=30 but 30 is not an option

Answer 7

Since we're finding the area of a square, all the sides are the same, so we'll multiply by the same number.

Answer 8

30*2???

so basically 5*5

Answer 11

Yep, and once you multiply that, there are 6 sides. So you can multiply the product of 5x5 by 6 or you can add the product of 5x5 6 times.

Answer 12

25*6??

Answer 13

You got it. What do you get when you multiply that together?
