Answer:
The value of x = 1 unit and y = 0.5 unit.
Explanation:
A square has a side size 3y and a diamond has a side size x+2. Knowing that y is equal to half of x and that the perimeter of the diamond is twice the perimeter of the square, the values of x and y are
Side of square = 3 y
side of diamond = x + 2
y = x/2
x = 2 y
Perimeter of diamond = 2 x perimeter of square
4 (x + 2) = 2 x 4 x 3 y
4 ( 2 y + 2) = 24 y
8 y + 8 = 24 y
16 y = 8
y = 0.5
x = 1
So, the value of x = 1 unit and y = 0.5 unit.
