Aiden calculated the area of triangle QRS below by finding half the product of 1.5 and 1.1.

Triangle Q R S has a base of 5.4 and a height of 1.1. Another side has a length of 1.5.

What error did Aiden make?
Aiden should have found half the product of 1.1 and 1.2 because the 1.5 line is not a dotted line in the figure.
Aiden should have found half the product of 1.1 and 5.4 because the 1.5 line is not perpendicular to the 1.1 line.
