Answer 2

Answer:

Step-by-step explanation:

Since, a rectangle has equal opposite sides,

2y = x + 4

⇒ x - 2y = -4                    ----1

2x + y + 8 = 4x - y

2x - 2y - 8 = 0

⇒x - y - 4 = 0                    -------2

subtracting 1st and 2nd equations

x - 2y - x + y + 4 + 4 = 0

y = 8

substituting in 1

x - 8 = 4

x = 12

Length of the rectangle = 4x - y = 4(12) - 8 = 40 units

Breadth of the rectangle = x + 4 = 16 units

∴Perimeter of the rectangle = 2(l + b) = 2(40 + 16) = 2(56) = 112 units

 Area of the rectangle = L x b = 40 x 16 = 640 sq. units
