A) 70\[c{{m}^{2}}\]
B) 140\[c{{m}^{2}}\]
C) 210\[c{{m}^{2}}\]
D) 420\[c{{m}^{2}}\]
Correct Answer: C
Solution :
[c] Area of the triangle = \[\frac{1}{2}\] perimeter \[\times \] radius \[2\,\pi r=88\]so \[r=\frac{88}{2\times \frac{22}{7}}=14\] \[\therefore \] Area of the triangle \[=\text{ }14\times 15=210\]cm2You need to login to perform this action.
