Help me please, its due at night today!!!

Answer 1

Explanation:

Area of polygon = area of square + area of triangle

Square:

Side = 12 cm

Area of square = side *side

= 12 * 12

= 144 sq.cm

Triangle:

base (b) = 12 cm

Height h = 19 cm

`Area =(1)/(2)bh\\\\=(1)/(2)*12*19\\`

= 6 * 19

= 114 sq.cm

Area of polygon = 144 + 114 = 258 square cm
