The axis of symmetry is x=2.
Well to get to the point
21 / 7= 3
So I then would multiply the 3 by 3 which would give me 9
And just to check your answer 7 x 3 is 21
So your answer would be 9

Answer:
10 in.
Step-by-step explanation:
The area of a rhombus is the product of the lengths of the diagonals divided by 2.
Let the diagonals be x and y.
area = xy/2
Here you have
area = 40 in.^2
x = 8 in.
We are looking for y, the other diagonal.
xy/2 = area
(8 in.)y/2 = 40 in.^2
(8 in.)y = 80 in.^2
y = 10 in.
Answer: The other diagonal has length 10 in.
