Answer 1

$<h2><font color = red > hey there$

$<font color = black > here we go....$

⊙ 1 mm = 0.1 cm




250 mm = 250*0.1 = 25 cm

Now ,

⊙ 1 m = 100 cm

1.5 m = 1.5 *100 = 150 cm

so , the area is
$l \times b \\ \\ 25 \times 150 = 3750cm {}^{2}$

Answer 2

Answer:

Perimeter of Rectangle=2(L+B)

=2(250mm+1.5m)

=250mm=(250/10)cm

=25cm

=1.5m(1.5*100) cm

=150cm

=2(25+150)cm

=2*175cm

=350 cm

Correct answer is 350 cm.
