Recall that a square is just a rectangle with all sides equal.
and the area of a rectangle is just length * width.
Triangle A is an Isosceles
Triangle B is Equilateral
Triangle C is Scalene
Hello there (I can do this one, it's quick enough)
The correct answer is 24 inches
There are 8 short sides, so you would do 1.5 times 8, to get 12 inches
There are 4 long sides, so you would do 3 times 4, to get 12 inches
12 plus 12 = 24 inches
I hope this helped
