Answer:
1) triangular garden is larger
2) 1.46 square feet
3) 56.5 square inches
4) 557.1 sq in
5) 216 sq in
Step-by-step explanation:
1) Area of circlular garden: 78.54
Area of triangle garden: 80
2) 80 - 78.54 = 1.46
3) 12/2 = 6
[tex]6^{2}[/tex][tex]\pi[/tex] = 113.1
113.1/2 = 56.5
4) area of square: 20(20) = 400
area do semicircle: [tex](20/2)^{2} \pi[/tex]/2 = 157.1
400 + 157.1 = 557.1
5) square: 144
triangle: 144/2 = 72
144 + 72 = 216
