Answer 1

Ans. B.1 (i)
$area \: \: = \frac{1}{2} bh \\ \: \: \: \: \: \: \: \: \: \: \: \: = \frac{1}{2} \times 6 \times10 \\ area \: \: = \: 30 \: sq. \: meter$
(ii)
$area \: \: = \frac{1}{2} bh \\ 210 = \frac{1}{2} \times 35 \times h \\ h = \frac{210 \times 2}{35} \\ h = 12 \: cm$

$area \: \: = \: \frac{1}{2} bh \\ \: \: \: \: \: \: \: \: \: \: \: = \frac{1}{2} \times 47 \times 31 = 728.5 \: sq. \: meter$
