Answer:
180 cm2
Area of a polyhedron:
15(=base)x12(=height)
=180cm2
btw parallelogram is a 2D pic how you can come out a ''base'' and ''height''? It should be called a polyhedron. Your question is weird.
If so, your ''area of parallelogram'' is 15cm2 since your question is hecking weird.
Btw it's 15cm2 not 15
Please check ur question b4 u ask
Answer:
Step-by-step explanation: 2(3x-4) so it would be 6-4 which is 2
Note that he diagonals<span> of a rhombus are </span>perpendicular<span> bisectors of each other.
slope = (3+1)/(6+4) = 4/10 = 2/5
the other diagonal slope = -5/2
midpoint of the diagonal is where the two diagonals meet.
midpoint ((-4+6)/2, (-1+3)/2) = (1, 1)
equation of the other diagonal line:
y = mx + c
y = -5/2 x + c
at (1,1)
1 = -5/2(1) + c
c = 1 + 5/2 = 7/2
y = -5/2 x + 7/2
2y = -5x + 7
</span><span>
</span>
You got it wrong again it is c. you can see this because it is the only one that has two negative numbers like the expression.
