Intro.
Before we solve the areas of the triangles, let's review the key points.
Key points:
- Area of triangle: 1/2 x Base x Altitude
Solution (4):
- 1/2 x 13.5 x 10.6
- => 1 x 13.5 x 5.3
- => 71.55 cm²
Solution (5):
- 1/2 x 7.2 x 4
- => 1 x 7.2 x 2
- => 14.4 yd²
Solution (6):
- 1/2 x 6 x 5.2
- => 1 x 3 x 5.2
- => 15.6 ft²
