Question 1148756
<br>
The perimeter of the square is 116 yards = 348 feet; so the side of the square is 348/4 = 87 feet.  The area of the whole yard is then 87^2 = 7569 square feet.<br>
The rock garden has a diameter of 50 feet, so a radius of 25 feet.  The area of the rock garden in square feet is then {{{(pi)(r^2) = 625(pi)}}}.<br>
The area of the grass is the area of the whole garden, minus the area of the rock garden.<br>
Do the calculations in square feet as directed; the area is square yards is the area in square feet divided by 9 (the number of square feet in a square yard).<br>
