Units and Area Review

1. b stands for “base,” which is the longest side of the triangle

1. b stands for “base,” which is the side perpendicular (at a right angle to) the height

1. b could be any of the side lengths; we just picked 18

1. h stands for “height,” which is never one of the sides of the triangle

1. h stands for “height,” which is the shortest side of the triangle

1. h stands for “height,” which is the perpendicular distance from the base to the opposite corner

1. No

1. Yes

1. Yes, but the height would be different

1. Because the area unit that goes with inches is square inches or in^2

1. Because b and h are both inches, and inches x inches will be in^2

1. in^2 is the wrong unit

$$A=l\cdot w$$

$$A=\pi r^2$$

$$A=\frac{1}{2}bh$$
