All you have to do is add up all of the sides.
then once you have X, for part 2 all you need to do is replace X with 4 and then solve
The answer is D :) hope this helped
Answer:
140
Step-by-step explanation:
Area of a rhombus = GE * HF / 2
Since, ED = 10, GE = 2* ED. SO, GE = 20
Since, FD = 7, HF = 2*FD. SO, HF = 14
So, 20 * 14/2
=> 10 * 14
=> 140
The answer would be a positive 15.1 or +15.1 because the positive number is greater than the negative which would make your answer positive, thats why you got it wrong :)
