Given
area of equi. triangle=4√3 cm square
let side be a
area of equi. triangle=√3/4 side square
according to question
4√3 cm square=√3/4 a square
√3 a square =4*4√3cm square
a square=16√3cm square
a square=16√3/√3cm square
a =√16cm square
a=4cm
hence, side of equilateral triangle=4cm
perimeter of square=3a
=3*4cm

Answer:
Answer
Vertices(±5,0)Foci(±7,0)
a=±5 and ae=±7
And e=
