<h2>
AREA</h2>
The formula for finding area of a square is:

In a square, all the sides are the same. Each side is 6 meters long. Plug in 6 to the formula.

Multiply:

The area of the square is 36 m²
<h2>PERIMETER</h2>
Perimeter is the distance around a shape. To find perimeter, you have to add all all the side lengths. The formula for finding perimeter is:

Remember that squares have 4 sides, and all length(s) and width(s) measure the same. The length and width measure the same. Plug in the numbers into the formula:

Simplify:

Add:

The perimeter of the square is 24 m
Answer:
The same thing but with y
Step-by-step explanation:
Answer:
slope = - 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c (m is the slope and c the y- intercept )
Given
5x + y = - 9 ( subtract 5x from both sides )
y = - 5x - 9 ← in slope- intercept form
with slope m = - 5
Parallel lines have equal slopes, thus
The slope of a parallel line to the given equation is m = - 5
