2 3/4 is greater then 2 2/3
4^3 = 64
log4 64 = 3
The exponent always comes to the other side.
The midpoint lines are half the opposite side length.
Line DE is given as 7 , So Line F = 7 x 2 = 14
Line EF is given as 12, so Line D = 12 x 2 = 24
Line DF is given as 16, so line E = 16 x 2 = 32
The perimeter is the sum of the 3 sides:
Perimeter = 14 + 24 + 32 = 70
25 = 5*5
405 = 81*5
therefore, 25/405 = (5*5)/(81*5)=5/81
