1a) To find the total area, you must find the area of the triangular part that is missing, then subtract this from the area of the rectangle. For the triangle’s area, you need to know the width (2m) and length (2m). For the rectangle’s area you need to know the width (3m) and length (4m).
1b) the total area is 10m^2 (10 meters squared). This is found by subtracting the triangle (.5x2x2=2) from the rectangle (3x4=12).

Step-by-step explanation:

Answer: y=7.5+-5

Step-by-step explanation:

Divide 3y from itself and -15 to cancel out the Y variable. So Y is equal to -5. Then you would be left with -2x=-15. So then you would have to divide -2x from itself and -15, which would give you 7.5, and that is your x variable.
