The area of an isosceles triangle is 45cm2 and the height is 5 cm. Find the perimeter of the triangle if the leg of the triangle is 2/3 cm. Plz give steps I'm really confused.

Circle d circumscribes abc and abe. which statements about the triangles are true? statement i: the perpendicular bisectors of abc intersect at the same point as those of abe. statement ii: the distance from c to d is the same as the distance from d to e. statement iii: bisects cde. statement iv: the angle bisectors of abc intersect at the same point as those of abe. a. i only b. i and ii c. ii and iv d. i and iii e. iii and iv
