A) \[60\,\,\text{c}{{\text{m}}^{2}}\]
B) \[55\,\,\text{c}{{\text{m}}^{2}}\]
C) \[50\,\,\text{c}{{\text{m}}^{2}}\]
D) \[40\,\,\text{c}{{\text{m}}^{2}}\]
Correct Answer: A
Solution :
Let each equal side = a = 13 cm and base b = 24 cm \[\therefore \] Area of the triangle\[=\frac{1}{2}b\cdot \sqrt{4{{a}^{2}}-{{b}^{2}}}\] \[=\left[ \frac{1}{4}\times 24\times \sqrt{4\times 169-24\times 24} \right]\text{c}{{\text{m}}^{2}}=60\,\,\text{c}{{\text{m}}^{2}}\]You need to login to perform this action.
