Answer:
If you're asking what the perimeter is:
C 32cm
If you're asking what the length of a side is:
A 8cm
Step-by-step explanation:
Area of a square is calculated by length x width.
And all four sides of a square are equal in length.
Area: 8cm×8cm=64cm2
Perimeter: 8cm + 8cm + 8cm + 8cm= 32cm
Another way to find the length of the sides would be to take the square root of 64. I believe that only works with the area of a square though.
√(64)=8

Answer:
-12xy-8y^2
Step-by-step explanation:
(6x+4y)-2y
distribute -2y into the terms
-12xy-8y^2
Recall that the interior angles of a quadrilateral add up to 360 degrees.
1) Let x be the measure of the missing angle, then we can set the following equation:

Solving for x we get:

2) Let y be the measure of the missing angle, then we can set the following equation:

Solving for y we get:

Answer:
1) 100 degrees.
2) 58 degrees.
