Answer 2

Step-by-step explanation:

$</p><p>Height\: of \:Meghana's \:Shadow(cm) \\</p><p>= 4*100 + 50\\</p><p>= 400+50\\</p><p>=450 cm\\</p><p>\\</p><p>Height\: of \:Tower's \:Shadow(cm)\\</p><p>=36*100\\</p><p>=3600 cm\\</p><p>\\</p><p>Height\: of \:Meghana's (cm) \\</p><p>= 1*100+30\\</p><p>= 130 cm\\</p><p>\\</p><p>Let \:the\: height\: of \:the\: tower\: be\: 'x'cm\\</p><p>$

$\frac{130}{450} = \frac{x}{3600}$

$\frac{130 \times 3600}{450} = x$

$130 \times 8 = x$

$1040 = x$

$∴ \: x = 1040$

$Height \: of \: the \: tower(m) \\ = \frac{1040 }{100} \\ = \: 10.4 \: m$
