Question
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.
Aiden should have found half the product of 1.5 and 1.2 because the 1.1 line is not perpendicular to the 1.5 line.
Aiden should have found half the product of 1.5 and 5.4 because the 1.1 line is a dotted line and not part of the figure.

To find the area of triangle QRS, the correct formula is to take half the product of the base and the height. In this case, the base is 5.4 and the height is 1.1.
Aiden incorrectly calculated the area using 1.5 (which is another side, not the height) and 1.1 (which is indeed the height). The height is necessary to compute the area correctly, and it must be perpendicular to the base.
The correct calculation Aiden should have made is half the product of the base (5.4) and the height (1.1).
Therefore, the correct answer is:
**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.**
