What does 'mass' in the word 'mass media' mean?

Tomato plus carrot plus cabbage plus (3 * carrot) = 113.04 feet

1x+1x+1x+3 x= 113.04
6 x = 113.04
x = 113.04 / 6 = 18.84 feet of fence = circumference 

The circumference of the tomato, carrot and  cabbage gardens is  18.84 feet each. the circumference of the strawberry garden will be 3 times larger or 3 x 18.84 = 56.52 feet.

With the circumference we can find the diameters, and with the diameters we can find the areas.

For the 3 small gardens, d = c/π
d=18.84 / 3.14
d=6  and the radius is 3 feet
Area = πr²
A = 3.14 x 3 x 3 = 28.26 square feet in each of the 3 small gardens

For the larger garden
d=6x3 = 18 feet and the radius is 9 feet
Area = πr²
A = 3.14 x 9 x 9 = 254.34 square feet in the larger garden
