Answer:

Area = Area of bigger triangle - Area of small triangle

${ \rm{area = ( \frac{1}{2} \times b_{b} \times h_{b}) - ( \frac{1}{2} \times b_{s} \times h _{s} )}} \\ \\ { \tt{area = ( \frac{1}{2} \times 18 \times 7) - ( \frac{1}{2} \times (18 - 13) \times 7) }} \\ \\ { \tt{area = (9 \times 7) - (2.5 \times 7)}} \\ \\ { \underline{ \tt{ \: \: area = 45.5 \: \: sq \: units \: \: }}}$

Area = area of square + area of two right angled triangles

${ \tt{area = (s \times s) + 2( \frac{1}{2} \times b \times h)}} \\ \\ { \tt{area = (6 \times 10) + (3 \times 5)}} \\ \\ { \underline{ \tt{ \: \: area = 75 \: \: {m}^{2} \: \: }}}$
