Here is your answer..

1} ➡️ Side = 8cm

Perimeter of square = 4 × side = 4 × 8 = 32cm

Area of square = side × side = 8 × 8 = 64 cm^2

2} ➡️ length = 2x

Breadth = x

Perimeter of rectangle = 2 ( l + b)

30. = 2 ( 2x + x)

30 = 4x + 2x = 6x

30/6 = x

5 = x

So, length = 2x = 2 × 5 = 10cm

Breadth = x = 5cm

Area of rectangle = length × breadth = 10 × 5 = 50cm^2
