1. 1/4(x+3)=12=X+3-12*4/4=X-45/4. Then, x-45/4=0. So, 1. X=45. 2. x+4/3=12=3x-32/3*3=0*3. 3x-32=0. You add 32 to each sides. 3x=32. x=32/3. Therefore, 1. x=45 and 2. x=32/3
The radius will equal half of the length of a side of the square.
The length of the side for this square lawn = √200 so the radius will be 1/2 * √200.
Answer 7.07 feet (to nearest hundredth.
