Answer:
VY = 21
Step-by-step explanation:
The perimeter of the rectangle below is 102 units. Find the length of side VY.
Write your answer without variables.
102 : 2 = 51 (semiperimeter)
3x + 4x + 2 = 51
7x = 49
x = 49 : 7
x = 7
VY = 3x
VY = 3 x 7
VY = 21
------------------------
check
find the other side
4x + 2 =
28 + 2 = 30
30 + 30 + 21 + 21 = 102
the answer is good
