Answer 1

Answer:

128cm²

Step-by-step explanation:

so first calculate area rectangle in between those triangles = 10cm × 8cm = 80cm².

now, lets calculate area of triangle = $\frac{ 1}{2} × 6 × 8 = 24cm²$

hence, there are two same triangles multiply the triangle area with 2 that is:

24cm² × 2 = 48 cm².

so, area of whole polygon = area of rectangle + area of triangles = 80cm² + 48cm² = 128cm²

hence, area of polygon is 128cm².
