If by the ellipses you mean to say that the number 7 repeats forever after that point, then it is not irrational. Any number which can be expressed with repeating decimals is not irrational. For example, pi is an irrational number because it has no repeating decimals, but 0.33333333... is not irrational because it can be expressed by simply saying 0.3 repeated.

Can someone pls help ​
algol13

Answer:

square so all sides are equal

bc^2+mc^2=bm^2

16x^2+4x^2=20x^2=2root5x

nd^2+dm^2=nm^2

x^2+4x^2=5x2=root5x

then:-

1/2*b*h=1/2*2root5x*root5x

=1/2*10x^2=5x^2
