Answer 1

Step-by-step explanation:

The following are the area formulae for the above figures

Figure 1 - Area-½×bh

Figure 2 -

$\sqrt{s(s - a)(s - b)(s - c)} \: \: \: \: \: \: \: \: (where \: s = \frac{a + b + c}{2} )$

Figure 3-

$\frac{ \sqrt{3} }{4} \times{a}^{2} (where \: a \: stands \: for \: each \: equal \: side)$

Figure 4 - ½×a×c

Figure 5 - b×h

Figure 6 - l×b

Figure 7 - ½×d1×d2
