Answer 1

Step-by-step explanation:

Area and Perimeter Formula Chart

Figures Area Formula Variables

Area of Rectangle Area = l × w l = length w = width

Area of Square Area = a2 a = sides of the square

Area of a Triangle Area = 1/2 b×h b = base h = height

Area of a Circle Area = πr2 r = radius of the circle

Answer 2

$= \geqslant area \: of \: square = \\ \: \: \: \: \: \: \: \: \: \: side \times side$

$= \geqslant perimeter \: of \: square \: = \\ \: \: \: \: \: \: \: \: \: \: \: \: 4 \times side$

$= \geqslant area \: of \: rectangle = \\ \: \: \: \: \: \: \: \: \: \: length \times breadth$

$= \geqslant perimeter \: of \: rectangle = \\ 2(length + breadth)$

$= \geqslant area \: of \: circle \: = \\ \: \: \: \: \: \pi {r}^{2}$

$= \geqslant perimeter \: of \: circle \: \\ or \: circumference \: \\ of \: circle = 2\pi r$

$\geqslant \: verified \: \leqslant$
