Question

how to find height of isosceles triangle whose perimeter and base is given.

Answer 1

example
By using the Pythagoras theorem

Explanation:

Draw the triangle first, The height is 15 and base is 16. Cut the triangle in half and you will end up with two triangles with a height of 15 and base of 8. Use the Pythagoras theorem and get the slant height. a2=b2+c2 By using this equation you will find the slant height 
x2=152+82 simplify this and you will get 17 dm. perimeter=17+16+17=50dm
