The area of triangle ADE is probably half of triangle ABC, so the perimeter would be 15 units, and the area would be 45 units squared.
<span>C) The triangles could have the same shape but not necessarily the same size.

Answer:
E, B and A
Step-by-step explanation:
we have <D = (7x-1)° , <A =(5x+25)°
{ all angles of square is equal to 90° }
<A + <D = 180°
5x + 25 + 7x - 1 = 180°
12 x = 180 - 24
12x = 156
x = 13
<A = (5*13 +25) = 90
< D = ( 7*13-1) = 90
so ABCD is a square
