Answer 1

Answer:

Step-by-step 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

$Area =\frac{1}{2}bh\\\\=\frac{1}{2}*12*19$

= 6 * 19

= 114 sq.cm

Area of polygon = 144 + 114 = 258 square cm
