Asquare has side lengths of 9, which of the following is a correct formula for finding the area of a square? select all that apply. a=9^2 a=ï€(9^2) a= 9 . 9 a= 1/2 (9) (9+9) a= 1/2 (9) (9)

A.

C.

D.

Step-by-step explanation:

We have been given that a square has side lengths of 9. We are asked to choose the correct options that represent area of the given square.

We know that area of a square is square of its each side.

, where a represents each side of the square.

Upon looking at our given choices, we can see that option A is the correct choice as our given square has length of 9 and square of 9 is correct.

We can write area formula as:

Therefore, option C is correct choice as well.

Upon simplifying option D, we will get:

Therefore, option D is correct choice as well.

Upon simplifying option E, we will get:

Therefore, option E is not a correct choice.

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.
