Hello Mate!
2y = x + 4
2y - x - 4 = 0 -----(1)
2x + y + 8 = 4x - y
-2x + 2y + 8 = 0 ------(2)
Multiply -1 by (2)
2x - 2y - 8 = 0 -------(3)
Adding (1) and (3)
x - 12 = 0
x = 12
Keeping value of x in (1) eq.,
2y - 12 - 4 = 0
2y = 16
y = 8
Length of □ = 4x - y or 4 × 12 - 8
= 40
Breadth = 2y or 2 × 8 = 16
Perimeter = 2 ( l + b )
= 2 ( 40 + 16 )
= 112 units
Area = 40 × 16 = 640 unit^2
Hope it helps☺!
