Question

I need help how to solve this problem

Answer 1

Ok, so shaded=big-2squares

big=8*12=96
shaded=71
71=96-2squares
minus 96 both sides
-25=-2squares
divide both sides by -2
12.5=square

the area of eqch square is 12.5 square cm
area=side^2
area=12.5
side^2=12.5
sqrt both sides
side=√12.5 cm

the dimentions of each side of each square is $\sqrt{12.5} \space\ cm$
