To find the length of g, we would use the Pythagorean theorem which states that in a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
So, using the Pythagorean theorem, we have:
g^2 = e^2 + f^2
g^2 = 9^2 + 40^2
g^2 = 81 + 1600
g^2 = 1681
Taking the square root of both sides to find g:
g = √1681
g = 41
Therefore, the length of g is 41 cm.
