Question

Find perimeter . Simplify your answer

Answer 1

perimeter of triangle=sum of all three sides

Explanation:

`( {2y}^(2) - {2x}^(2) ) + ( {y}^(2) - {x}^(2) + 11 ) \\ + ( {5x}^(2) - {2y}^(2) - 12)`

`{2y}^(2) + {y}^(2) - {2y}^(2) + {5x}^(2) - {x}^(2) - {2x}^(2) + 11 - 12`

Hope it helps you<3

`{y}^(2) + {2x}^(2) - 1`
