Order each of the following areas from greatest to least.

Question

Square with a side length of 4
Square with a side length of 2
Equilateral triangle with a side length of 4
Circle with a radius of 2
Circle with a radius of 4

Answer 1

Use 3.14 for pi

Draw a height for equilateral triangle (30-60-90 right triangle) = 2(rad3) = 3.46

Area of circle = (pi)r^2

Area of triangle = (.5)b(h)

Area of square = s^2

 

Area of circle 2 = 50.24 units

Area of square 1 = 16 sq units

Area of circle 1 = 12.56 sq units

Area of triangle = 6.93 sq units

Area of square 2 = 4 sq units
