Answer 1

They are simple and you can do it on your own. I will tell you the formulas for doing so:

Perimeter of a rectangle = 2 × (length+breadth)

Area of a rectangle = length × breadth

Area of a square = side × side

Side of a square = √area

Side of a square = perimeter / 4

Volume of a cuboid = length × breadth × height

1dm = 10cm

Volume of a cube = $Side^{3}$ or side × side × side
