The yellow area is 27, the green area is 35 and the red area is 40. What is the blue area?

call other triangles x y z and w to the blue

@idle zodiac How did you get that result? I don't have the answers unfortunately

#

But it gives an integer with x = 27 and y = 40 so I guess it's right

#

Thanks for your time btw

#

you just name the sides

#

lets go with red triangle for example

#

I will say a is the short side of the rectangle which is base of the red triangle.

#

I will say b to the height of that red triangle

#

so a*b/2 = 27 so b = 54/a

#

you keep naming the sides like this and you'll have few equations

#

I can send you a video about t

Thank you

#

I just solved it by taking the factors of the sides, got ab = 180 and found the inner triangle (assuming sides are integers)
