Answer 1

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
