Question

a rectangle whose length is = to 30cm and breath=0.2m​

Answer 1

${\huge{\boxed{\fcolorbox{red}{gold}{Answer\checkmark}}}}$

$\rm \star \: length \: (l) \: = 30cm \\ \\ \star \rm \: bredth \: (b) \: = 0.2 m = \: 20cm$

$\star \rm \: Area \: of \: rectangle \: = \: l \times b \\ \\ \implies \: 30 \times 20 \: \rm{cm}^{2} \\ \\ \implies \: \pink{600 \: \rm {cm}^{2} }$

$\star \rm \: Perimeter \: of \: rectangle \: = 2(l + b) \\ \\ \implies \: 2(30 + 20) \: \rm \: cm \\ \\ \implies \: 2 \times 50 \rm \: cm \\ \\ \implies \rm \pink{100cm}$

Answer 2

To find Perimeter:-

perimeter = 2 (length+breadth)

perimeter = 2 (30 + 20) cm

perimeter = 2 × 50cm

perimeter = 100cm

To find Area:-

area = length × breadth

area = (30 × 20) cm

area = 600sq.cm

this is the answer of this question.
