EXPAND THE BRACKETS. 
1st value in the 1st bracket multiplied with the 1st value in the 2nd bracket plus the 1st value in the first bracket multiplied with the 2nd value in the 2nd bracket etc.
So...
(x^2 X 2x^2) + (x^2 X x) + (x^2 X -1) + (4 X 2x^2) + (4 X x) + (4 X -1)
 = 2x^4 + x^3 - x^2 + 8x^2 + 4x - 4
 = 2x^4 + x^3 + 7x^2 + 4x - 4

I need help with this problem
Anarel [89]

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
