Find the area of the polygon.
zalisa [80]

Answer:

A=128\ cm^2

Step-by-step explanation:

we know that

The area of the polygon is equal to the area of a square plus the area of four congruent triangles

so

A=b^2+4[\frac{1}{2}(b)(h)]

where

b=8\ cm\\h=4\ cm

substitute

A=8^2+4[\frac{1}{2}(8)(4)]

A=64+64=128\ cm^2
