Answer:
C.) 413 cm^2
Step-by-step explanation:
To figure out the area of a square, much like a rectangle we multiply length × width. In this case because the length and width are the same (definition of a square) then it's simply 
and 8 inches is 20.32 cm (8x2.54):
a.) 413 cm^2
Yes it does because in order to find out if a triangle is a right triangle, you can use the Pythagorean theorem.
sqrr 2 squared + sqrr 2 squared= 2 squared
simplify this:
2+2=4
because the equation is correct, this can make a right triangle
Im not good at this, thought Ive done Geometry, But for the first one (180-70) which should be 110, and for the second one I would say 55.
