Hans wanted to find the length of the hypotenuse of the triangle, which statement correctly identifies his error?

40 cm

cm

& 445 m²

81480-6

181 - ²

181 cmc

he did not square 40, he just multiplied by 2

he did not finish the problem. he should have divided 161 by 2 to find the square root.

he should have added 9 + 9 to find the value of g?

he should have subtracted the two squares to get 40 -9. because numbers get too large if both legs are squared and then added together
