A) \[\text{3}0\text{8 }{{\text{m}}^{\text{2}}}\]
B) \[\text{154 }{{\text{m}}^{\text{2}}}\]
C) \[\text{616 }{{\text{m}}^{\text{2}}}\]
D) \[\text{77 }{{\text{m}}^{\text{2}}}\]
Correct Answer: D
Solution :
| Diameter of semi-circular region of the garden bed \[=14m\] |
| \[\therefore \] Radius of the semi-circular end \[=7m\] |
| So, Area of one semi-circular end \[=\frac{1}{2}\times \pi {{r}^{2}}\] |
| \[=\frac{1}{2}\times \frac{22}{7}\times {{7}^{2}}=77{{m}^{2}}\] |
| So, option [d] correct. |
