So I need help because I'm honestly confused. This is like half of my math grade. How do you find the area of your shapes? (Triangle, Circles, Rectangles, Square, Polygon, Trapezoid) etc.

Area of Triangle: bh

Area of Circle:

Area of Rectangle: l×w

Area of Square:

Area of Polygon:

Area of Trapezoid: ×h

Step-by-step explanation:

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
