Point B,DB,D and JJ are midpoints of the sides of right triangle ACGACG . Points K,E,IK,E,I are midpoints of the sides of triangle JDGJDG, etc. If the dividing and shading process is done 100 times (the first three are shown) and AC=CG=6AC=CG=6, then the total area of the shaded triangles is nearest

A square and a triangle have equal perimeters. The lengths of three sides of the triangle are 6.2cm, 8.3cm and 9.5cm. The area of the square is...
Perimeters of a triangle is: 6.2+8.3+9.5=24cm
But a square and a triangle have equal perimeters
⇒Perimeters of a square is 24cm
So: the side of a square=\(\dfrac{24}{4}\)=6
Other way: the area of a square=a.a
⇔Ssquare=6*6=36 (cm2)
