The number of isosceles Deltas with integer sides if no side exeeds 2016 isA. `(1008)^(2)` if equal sides do not exceed `1008`B. `2(1008)^(2)` if equal sides exceed `1008`C. `3(1008)^(2)` if equal side have any length exceeding 2016D. `(2016)^(2)` if equal sides have any length not exceeding 2016 |

Answer» Correct Answer - A::B::C::D If equal side have length `n`, then the number of triangles will be `2n-1`. So if equal side does not exceed `1008,` no. of triangles `=1+3+5+…1008` terms `=(1008)^(2)` if equal side does exceed `1008`. No of triangles `=2016+2016+2016+…1008` terms `=2(1008)^(2)` |
