Answer 1

Step-by-step explanation:

Figures Area Formula Variables

Area of Rectangle Area = l × w l = length

w = width

Area of Square Area = a2 a = sides of the square

Area of a Triangle Area = 1/2 b×h b = base

h = height

Area of a Circle Area = πr2 r = radius of the circle

Area of a Trapezoid Area = 1/2 (a + b)h a =base 1

b = base 2

h = vertical height

Area of Ellipse Area = πab a = radius of the major axis

b = radius of the
