Answer:
hey here is your answer
so pls mark it as brainliest
Step-by-step explanation:
now as the given square is divided in four equal triangles
their area would also be equal
so thus then by area addition property
area of required square=sum of area of all four triangles
so as here area of one of the triangle is 9
the area of other three triangles would also 9 unit.square each
hence area of required square=4×9
=36unit square
so now we know that area of square=side square
hence side square=36
taking square roots on both sides we get
side=6 units
hence side of required square is 6 units
