b. Square
c. Triangle
d. Rectangle

Answer 1

The Option that gives you more rock for the money is the Circle

Explanation:

We must find the area of the circle and the square

`A Circle = \pi *rx^(2)`

`r= (15)/(2)`

`A Circle = \pi *(7.5)^(2) \\A Circle = 176 Inch^(2)`

`A Square = 12*12 = 144inch^(2)`
