Answer 1

Answer:

85.71 cm square

Step-by-step explanation:

area of square=s*s

                       =8*8=64 cm square

area of equilateral triangle= $\sqrt{3}$/4 $a^{2}$

                                            =$\sqrt{3}$/4* 8*8=$\sqrt{3}$/4*64

                                            =21.71 cm square

total area=64+21.71=85.71 cm square
