It's okay if you don't know all I know some of these but I wanna conform I'll mark BRAINLIEST the correct and fast answer​

Answer 1

$\huge\purple{Required \: Answer}$

$\huge{Square}$

Area - (Side) square

Answer 2

Answer:

area of square= side × side

peri. of square= 4 × side

area of rectangle= length ×breadth

peri of rectangular= 2( length × breadth)

area of ∆= 1/2 × height× breadth

peri. of ∆= side+side+side

area of semi circle= 1/2×π R square [ R represents radius]

peri. of semi circle= π R+2 R

area of circle= π R square

peri. of circle= 2 π R

area of oval= π ab [ a represents shorter radius and b represents longer radius]

peri. of oval= 2π√a square+ b square/2

Sorry the rest of the questions I don't know.
